Akubra - A classic Australian hat, usually worn by
farmers, politicians campaigning in the bush, or presenters on weekend 4WD shows. Sometimes worn with corks hanging from it, but usually only by buskers posing as traditional swagmen.
Beanies - A sometimes knitted hat that occasionally has
a pompom on the top to cover the loose threads. Children and old people tend to wear loud and gaudy ones, while those in between tend to wear plainer ones - occasionaly designer ones with a surf label stitched to the front. They are frequently worn at the footy. Originally designed to keep your head warm, but sometimes worn during armed robberies.
Pants - In Australia "pants" refers to the long type of clothing worn on your lower body - as in trousers, trackpants or trackydacks. It is different to "pants" as referred to in England. Whereas "George, get your pants on" would be generally said with less urgency in Australia due to the expected circumstance of being half-dressed (viz the in-laws are about to pay a surprise visit & George is vaccuming in his undies) it would simply mean George needn't hurry to finish dressing. In England George would be nude.

Pluggers - Another name for thongs (the footwear). As far as I'm concerned a plugger is the old school daggy rubber thongs, not the fancy grassy souled, "i'm sparkly and covered in beads".
Undies - Shortened form of 'Underwear' (the word, not
the garment). Also called grundies, briefs, knickers, jocks, bog-catchers, fart-filters, boxers and panties. In England they are referred to as pants, which are not to be confused with the Australian variation of pants. 
Ugg Boots - An originally Australia invention that was pinched by Hollywood. Chunky sheep skin lined boots that are popular in very cold places and in bogan communites (they look especially good with a baggy flannel shirt and a black beanie). Now widely accepted as good shoes to go grocery shopping in.
SINGLETS - The unofficial Australian national dress
uniform. The difference between Singlets, Vests and Tank Tops is dependent on how wide the shoulder "straps" are, and what fabric the garment is made of. Singlets can be worn under clothes, similar to an English Vest but can just as easily be worn as an outter garment. In fact, it is not unusual for male retirees to be seen watering the gerbras while wearing a singlet and often by young men wanting to give the impression that they are so hot that they needed to take their clothes off. More often than not they are white in colour, but the blue singlet is also a popular colour - particularly when slightly faded. The Blue Singlet is considered to be part of the national uniform. Singlets are sometimes referred to by the popular brandname 'Chesty Bonds'.
*Reader Tony C. of Pine Rivers (Oz) tells us that the blue singlet is actually called a "Jackie Howe" in tribute to the famous Australian shearer who according to legend, was wearing a blue singlet on the day he broke the shearing record.
TANK TOPS - In Australia, a Tank Top is a slight variation
on a singlet. Tank tops have wider fabric at the shoulders and don't tend to be as tightly fitted as a singlet. They are often worn in summer when it is too hot to wear a conventional T-shirt. Tank tops are available in a range of bright, gaudy colours and often come with illegible scrawlings about the beach on the front. The Australian Tank Top is different from the English Tank Top.
VESTS - Vests in Australia are very
different from the English Vests. Australian vests are probably more closely related to the English Tank Top. Vests tend to be knitted, or made of some sort of knit-fabric. Vest can be pull-ver the head style, or button/zip at the front. The term "String Vest" is however universal, as it means "bad fashion" in both hemispheres.
