A guide to the special birds found across Australia’s vastly varied landscapes.

From the eastern rainforests to the central deserts, Australia is home to some 900 species of birds. Finding Australian Birds covers over 400 birdwatching sites conveniently grouped into the best birding areas, from one end of the country to the other. This includes areas such as Kakadu in the Top End and Uluru in the Red Centre of the Northern Territory, the Great Barrier Reef in Queensland, an amazing diversity of forests along the eastern Australian seaboard, including some of the world’s tallest forests in Tasmania, the iconic Strzelecki and Birdsville Tracks in South Australia, and the mallee woodlands and remote Kimberley region in Western Australia.

Chapters are arranged by state or territory and begin with an overview. Birdwatching sites are then grouped by region to provide specific details on target species, access and useful information such as accommodation and facilities. This second edition includes over 30 new birdwatching sites and updated information on site access. The book also provides a comprehensive ‘Bird Finding Guide’, listing all of Australia’s birds with details on their abundance and where exactly to see them.

Finding Australian Birds will be valuable to both Australian birdwatchers and international visitors. It will assist novices, birders of intermediate skill and keen ‘twitchers’ to find any Australian species.

Praise for the first edition:

"Twitchers will find this a most agreeable companion but all bird-loving travellers should pop a copy in their backpack, along with good binoculars."
Susan Kurosawa, Weekend Australian, June 2014

"The amount of detailed information within its pages will be enough to make even the best-travelled birders eager to get out and check a few more sites"
Chris Watson, Australian Birdlife, June 2014

"This excellent birdwatching site guide by Tim Dolby and Rohan Clarke will save you time if you are planning an Australian birdwatching trip, and is sure to help you find more of your target species... you wouldn’t want to plan an Australian birding trip without consulting this one."
Michael Szabo, Birds New Zealand (16), December 2017

Includes:

• Fully updated second edition, featuring new sites and current site access details.
• Up-to-date information on 400+ good birding locations in Australia, written by experts with first-hand knowledge of the sites.

Authors:

Tim Dolby is a well-known Australian birdwatcher and guide, who has led multi-day birdwatching tours to remote parts of Australia for over a decade. He was the principal editor of Where to See Birds in Victoria, a comprehensive guidebook to some of the best birdwatching sites in the state.

Rohan Clarke is an ecologist at Monash University with a research focus on bird conservation and island ecosystems. He’s also a passionate birder, with a love of seabirds, and an author of both the award-winning The Australian Bird Guide and The Compact Australian Bird Guide.

For each species, the authors examine the many-and-varied common names and full scientific name, with derivation, translation and a guide to pronunciation. Stories behind the name are included, as well as relevant aspects of biology, conservation and history. Original descriptions, translated by the authors, have been sourced for many species.

As well as being a book about names, this is a book about the history of the ever-developing understanding of birds, about the people who contributed to this understanding and, most of all, about the birds themselves. This second edition has been revised to follow current taxonomy and understanding of the relationships between families, genera and species. It contains new taxa, updated text and new vagrants and will be interesting reading for anyone with a love of birds, words or the history of Australian biology and bird-watching.

Reviews:

"The wealth of meticulously researched information presented in this book makes it an essential reference for anyone keen about birds and words, and a very welcome addition to ornithological literature."
Virgil Hubregtse, The Victorian Naturalist 136(6), 2019

"This wonderful book by Ian Fraser and Jeannie Gray fills a niche in the available bird literature as it seeks, and achieves admirably, to explain in depth how the Latin and English names of our Australian birds came about. ...If you are wondering what a Dick, Dick, the Devil is, or a howling jackass, or even a doubtful reed-bellower, then this is the book for you."
Libby McGill, Western Australian Bird Notes 172, December 2019

"In truth there is little for the carping critic to cavil about. All in all, Australian Bird Names: Origins and Meanings is a most valuable reference work, rich in interesting information of a kind not easily found elsewhere. It is good to see that CSIRO Publishing appreciates the need to keep it up to date."
Kevin Windle, Canberra Bird Notes 44(3), December 2019

"At times amusing and always interesting, this book a would make an excellent addition to the bookshelf of anyone who is interested in birds, words or history."
Rhianna King, Landscope, Autumn 2020

"Birdwatchers with a thirst for knowledge about all manner of trivia and history will enjoy poring through hundreds of pages crammed with details."
John Peter, Australian Birdlife, December 2019

Swifty grows from a hatchling to a fledgling in the blue-gum forests of Tasmania. She is then ready to make a challenging migration, following the blossom trail across Bass Strait to mainland south-eastern Australia.

Swifty faces many threats and dangers, but she must return home. Will she make it?

Fly with Swifty in this beautifully illustrated story and learn how to spot a swift parrot and help protect them.

Reading level varies from child to child, but we recommend this book for ages 6 to 9.

Highly Commended, The MARION ACT Notable Book Awards 2023: Children's

Reviews:

"Swifty is beautifully illustrated by Astred Hicks. There is so much to learn in her illustrations from the fluffy down of newborn parrots to their feasting on lerps on leaves and sticky nectar from gum blossoms. The information pages at the back of the book, help to unlock the open questions in Swifty. There are also excellent teacher notes at the CSIRO publishing website. We have reviewed several of their books lately and the quality is high with all of them. Highly recommended."
Susanne Gervay, CBCA Reading Time, 25 September 2022

"Illustrator Astrid Hicks, also an award-winner, brings colour, joy and so much heart to the pages. Her illustrations are funky and detailed, and Swifty’s rainbow plumage shines bright one very page.
With detailed teachers notes to accompany it, this book is great for classrooms keen to learn about Australian wildlife. But it’s equally brilliant as a bedtime story, with or without the extra notes at the back...
Joyful, inspiring and engaging, Swifty the Super-fast Parrot is a winner."
Shaye Wardrop, Kids' Book Review, 3 October 2022

"Swifty is another wonderful book that provides younger readers with the opportunity to learn about one of Australia’s critically endangered birds through an engaging story. The stunning endpapers and glossy illustrations by Astrid Hicks perfectly complement the text and offer the reader so much to explore on each page."
Kathryn Beilby, ReadPlus, 3 October 2022

"This is a fictional tale full of interesting facts aimed at 6- to 9-year-olds. <...> This book touches on migration and what to do with an injured bird, as well as the factors contributing to the Swift Parrot being critically endangered - predation, by sugar gliders and cats, and habitat loss."
Sue Lashko, Canberra Bird Notes 47(2), 2022

"I loved reading this book out loud - so many wonderful adjectives and descriptive verbs to show the reader how the Swift Parrot moves about from a nest hollow with her babies to a migration north during Winter and then back down south to Tasmania to breed during spring and summer."
Vanessa RyanRendall, We Can! (email newsletter), 31 January 2023

Why do magpies swoop and why do we have such a fascination with them? Discover more about these clever, cheeky and charming songbirds through this delightful book.

Reading level varies from child to child, but we recommend this book for ages 5 to 9.

Reviews:

"An informative delight with a heartwarming story! I love that we have this wonderful book out in the world to celebrate and create more understanding around these clever, cheeky and charming songbirds."
Picture Book Book Club (Instagram), 16 August 2022

"This glorious picture book written by Nicole Godwin will become a firm favourite of younger readers. The striking end papers and bold illustrations by Susannah Crispe will delight the reader and perfectly complement the simple yet captivating text."
Kathryn Beilby, ReadPlus, 01 September 2022

"Crispe's illustrations are simply stunning. With beautiful soft colours and details galore, in only one setting (Magpie's tree at the park). Crisp creates an entire world, with multiple characters that have stories of their own lovingly weaved into their expressions, clothing and accessories. It's truly a delight to turn each page, meet a new character and imagine who they are and what has brought them to the park."
Shayne Wardrop, Kids Book Review, 02 September 2022

"Coupled with explanatory notes at the end and thorough teaching ideas which cover science, English, ethics and Aboriginal and Torres Strait Islander histories and cultures, this is a book that must be shared with every young student so they understand why magpies swoop, and that they are just like human parents in their desire to keep their babies safe."
The Bottom Shelf, 04 September 2022

"I love the brevity of Godwin’s text, with short, punchy sentences and a pattern around repetition of the word 'swoop'. And in Crispe’s vibrant illustrations, Magpie’s bold, proud image, with animated facial expressions, occupies centre stage alongside the busy activity of the park visitors and set against soft greys and greens of a lush Australian park background. <...> I highly recommend this book for 6-9 year olds, especially as a teaching resource to introduce discussions about birds or animal behaviour in general. There are teaching notes on the publisher’s website."
Barbara Swartz, CBCA Reading Time, 19 September 2022

"While only around 10 per cent of male magpies actually attack, their seasonal antics have becomes a part of Australian folklore. Nicole Godwin's spare, carefully crafted text provides opportunities for young readers to join in Magpie's "swooping", while Susannah Crispe's watercolour illustrations perfectly capture the character of the cheeky magpie dad <...> This is a fabulous way to help young people appreciate a magnificent bird that is an important part of our urban environment."

The TMB Super Plossl Series

The TMB Super Plossl series is a clear upgrade over the basic eyepieces supplied with most telescopes, offering sharper images, better contrast, and improved build quality at an accessible price point.

Using a classic 4 element Plossl optical design and a 50 degree apparent field of view, these eyepieces deliver bright, well corrected views across the field. Fully multi coated optics enhance light transmission and reduce internal reflections, helping planetary detail stand out more clearly and deep sky objects appear cleaner and more defined compared to standard kit eyepieces.

Each eyepiece features a standard 1.25 inch barrel with filter threads, solid metal construction, and protective caps, making them a dependable addition to any observing kit.

The TMB 25mm Super Plossl

The 25mm TMB Super Plossl is ideal for low to medium power observing, framing larger deep sky objects, and locating targets before increasing magnification.

Eye relief is comfortable and forgiving, making it an easy eyepiece to use for observers of all experience levels.

As a common focal length in many telescope kits, upgrading to a fully multi coated Super Plossl version can provide improved sharpness and contrast while maintaining a familiar magnification.

Saxon Slow Motion Control Cables deliver precise, hands-on adjustment for your telescope mount. Compatible with AZ, EQ3, and EQ5 mounts, these flexible cables enable smooth tracking and repositioning without disturbing your eyepiece view. Simply connect to your mount and gain the control needed for comfortable, extended observing sessions. Essential for serious stargazers seeking refined pointing accuracy.

Optolong L-Synergy Dual Narrowband Filter

The Optolong L-Synergy filter is designed for astrophotographers using DSLR, color CMOS, or CCD cameras who want to achieve stunning narrowband results without switching to a monochrome system. By pairing traditional dual-narrowband (Ha & OIII) concepts with a unique “Ha & OIII + SII & OIII” approach, L-Synergy overcomes the usual limitations of colour cameras and makes Hubble-Palette–style imaging accessible to everyone.

With this filter, you can produce deep, high-contrast SHO-like images of emission nebulae using your existing colour camera—no additional SHO filters or monochrome upgrade required. It’s an affordable way to achieve professional-level results even under bright suburban skies.

Why Choose the L-Synergy Filter?

The L-Synergy is a dual 7 nm narrowband filter engineered for telescopes with an f/ratio of f/3.3 or slower. Years of optical refinement have produced a design that suppresses bright star halos while delivering extremely high transmission in the key emission bands.

• Selective Narrowband Performance
  Transmits only the OIII (500.7 nm) and SII (672.4 nm) nebula emission lines, rejecting unwanted wavelengths and light pollution.

• Exceptional Contrast and Signal-to-Noise
  By isolating the oxygen and sulfur signals, the filter produces a darker background sky and dramatically improves contrast—especially valuable in heavily light-polluted environments.

• Light-Pollution Resistant
  Filters out the vast majority of urban skyglow, allowing astrophotographers to capture clean, detailed nebula structure from almost any location.

Optical Design

L-Synergy is precision-engineered based on the spectral behaviour of emission nebulae and common light-pollution sources. Its carefully tuned passbands maintain consistently high transmission in both SII and OIII, ensuring accurate colour capture and high-quality data for processing.

The result: a powerful, easy-to-use narrowband solution that unlocks deep-sky imaging performance far beyond what typical colour cameras can achieve, giving more astrophotographers access to true SHO-style imaging.

The James Webb Space Telescope took three decades from conception to launch but the wait has been worth it. The results of the most anticipated telescope of the 21st century have been nothing short of spectacular.

The idea for the James Webb Space Telescope (JWST) was first raised in 1989, well before the enormously successful Hubble Space Telescope was launched. The infrared telescope with a mirror larger than four meters was launched on Christmas Day 2021.

In the summer of 2022, NASA released the first scientific images from Webb to the amazement of more than 300,000 viewers who watched the event live, and hundreds of millions around the world who have viewed Webb's images since then.

Webb's Cosmos is written in the spirit of Terry Dickinson's enormously popular book Hubble's Universe, which has sold over 100,000 copies. This book contains both the classic Webb images that have already become famous and the latest images from the frontiers of science taken by Webb, some of which appear here for the first time.

Author Marcin Sawicki is a professional astronomer who is an active user of Webb's images and data. He brings a wealth of knowledge and personal experience to the book and explains the science behind the images in accurate but accessible and engaging language.

Webb's Cosmos first provides the needed historical and scientific background to understand how the telescope works and what it can do. The book then presents a curated selection of some 200 photographs with descriptive captions that narrate these images of the distant universe. Chapters include:

• Stars and gas clouds
• Galaxies both near and far
• Planets and our solar system

These Sky-Watcher Wide Field 2x54 Binoculars are an amazing way to experience the night sky. 

Sharp optics only magnify 2x, while offering large, 54mm, main lenses. This unique combination keeps your natural eyesight's wide field of view but allows you to see the night sky up almost two magnitudes fainter than what you can see normally. 

They have a 36 degree field of view, with an apparent field of field (AFOV) of a stunning 72 degrees. 

The unique binoculars will reveal:

• Countless stars, usually  hidden from your eyes
• Star clusters
• Milky Way star clouds
• Even galaxies!

Their lightweight construction makes them easy to hold even for extended observing sessions. The compact carry bag is included.

The M54-M48-2 adapter is mainly used for connecting to the 2”EFW and M54 filter drawer.

The thickness of this adapter is 2mm.
