Americans have Letter size paper and A4 paper is just a little longer and narrower than this.

Australians bet a lot on horse races, and they use a guide to the horses' previous achievements, called a form guide.  So if something runs according to form, it is behaving as expected.

A broad brimmed Australian hat, like a Stetson outdoor hat but with a wider brim and often shaped in a Western style.  I should just say high quality cowboy hat and be done with it!

Okay.  Everything's all right.  She'll be right, mate.

Anyhow.

Road surface.  Many Australians say bitumen which is also a type of blacktop but Sam is aware of the difference between bitumen and asphalt.  Americans might say pavement, but in Australia, pavement is a footpath, not a road surface.

Australian.  In Aussie Guards story #1, Sam teaches Quinn how to pronounce it.

Bathing suit.  Swim suit.  At least Sam didn't use the more graphic Australian term for tight male swimsuits: budgie smugglers.  Budgies are budgerigars, small parrots, which are often smuggled out of Australia for sale.  There is only one place in a tight swim suit where a man looks like he's hiding budgies.

Washroom.

"You little beauty!"  Excellent.

Bedside lamp, end table.

The dictionary meaning is to penetrate during anal intercourse, but Aussies use the term casually to mean anything from a disreputable man, to playing around, to an exclamation of annoyance.

Duvet.  Australians use a lot of different words for quilts. We used to say continental quilt or eiderdown or comforter. Doonas are a lot more common than they used to be but unless you keep the air conditioning on, they cannot be used on the bed in spring or summer.   See the Australian Writers' Centre article about the origin of the term doona.

Australia.  So named because in the world globe, it is in the southern hemisphere, down under the countries in the northern hemisphere.

The little bumps that form on skin roused due to cold or excitement used to be called goose pimples in Australia, because when you pluck a goose you get bumps that big on the carcass, and all lumps like that were called pimples.  However due to the success of a famous American horror series, more Australians call them goosebumps now.  To keep the Australian flavor, I have used the next most popular term, gooseflesh.

Australians generally say Monday to Friday and Americans tend to say Monday through Friday.

Mom. Actually, Mum is pronounced the same as Mom in both Australia and America.  Because the accents are different, it has to be spelt (spelled!) differently.

There is no purpose in doing that.  It would be pointless.

Yes.  Agreeing with the speaker while acknowledging a negative point.

Zero.

Honest.

Go for a walk or run.

Exclamation of surprise, originally God's truth!

Exclamation of emphasis.  Comes from May God strike me dead if I am lying.

This list only describes Aussie terms as they are used in the Aussie Guards stories.  There are longer lists at the back of each print book and in XRay for each eBook which include more obvious terms, like hubbie meaning husband.  There are more details again in the Sheila Strine discord for NSFW explanations.  That discord is only open to Sheila Strine Patreon members.

For readers interested in Aussie words in general, there are far longer lists of Aussie terms. For example, the Australian National University, School of Literature, Languages and Linguistics has a list with explanations at https://slll.cass.anu.edu.au/centres/andc/meanings-origins/all and a lot of travel consultants have put together lists of Aussie phrases, some of which are hilarious.

For those interested in South Australia specifically, there are generally held to be four South Australian dialects, and analysis of the Adelaide one may be found in The Global Council for Anthropological Linguistics: The Adelaide dialect in Australia language at https://glocal.soas.ac.uk/adelaide-dialect-in-australia/.  As an Adelaidean, I was surprised by some of their conclusions, which just goes to show how individuals have different language sets.
