Australia

Eucalyptus trees are everywhere, and utility poles are often made from eucalyptus wood too. Besides the green wooden poles, some are made of steel to resist termites.

Bollards' red reflectors are basically only on one side, and the red area is small — unlike New Zealand, where they're wrapped fully around front and back.

If a GIVE WAY sign has black lettering, it's Australia. Red lettering means New Zealand.

If the speed limit is shown on a narrow white plate, it's Australia.

There's a road-number sign format like "M1." South Africa uses the same format, but with a different font.

Christmas Island sometimes comes up. Google Car looks distinctive there, and yellow plates are common.

A tree whose trunk swells like a bottle at the base (boab). Its natural range is limited to the Kimberley region of Western Australia and eastward into the Northern Territory.

Coastal rainforest thick with palms and dark-green foliage points to the Wet Tropics of northern Queensland.

You can roughly narrow down the region from how the vegetation looks.

A grass whose stiff, needle-like leaves form round tussocks dotted across the ground (spinifex). If you see round green tussocks dotting red soil, you're in the dry interior.

A eucalypt shrubland (mallee) where a single "tree" actually branches into multiple stems right at ground level, staying under 10m tall. Found in semi-arid areas with winter rainfall, across Western Australia, South Australia, New South Wales, and Victoria.

Soil color can sometimes narrow down the region. The western coast has a lot of red soil, a semi-arid durisol.

Roads along the northwest coast tend to have especially red soil.

In the inland center, the soil color is fairly close to the western coast, but the grasses seem different.

Western Australia and Victoria have some utility poles shaped like a mountain.

A place that's completely flat to the horizon with not a single tree, just low, grayish saltbush stretching on — that's the Nullarbor Plain. It spans South Australia and Western Australia.

Brown, spiky, tower-like mounds jutting up out of grassland are termite mounds. Cathedral-shaped mounds are common in the Northern Territory.

If lush, rolling green pastures or dark, mossy forest feel unusually cool for the mainland, it's Tasmania. The west gets a lot of rain and still has temperate rainforest.

Tall sugarcane fields stretching along the coast point to Queensland.

The Wheatbelt north and east of Perth is a vast stretch of wheat fields and sheep pasture with the trees almost entirely cleared away. It grows drier and more pasture-focused toward its eastern edge.

Neatly trellised vineyards mean a wine region. South Australia accounts for over half of national production.

Reddish-brown rocky hills, blazing red soil, and a long single-track iron-ore railway point to the Pilbara in northern Western Australia.

Black terraced open-cut slopes, long trains loaded with coal, and black coal stockpiles point to a coalfield. The main ones are the Bowen Basin in central Queensland and the Hunter Valley in New South Wales.

Mining equipment and heaped waste rock amid red soil and sparse eucalypts points to Western Australia's Eastern Goldfields (around Kalgoorlie and others).

License plate colors might tell you the region, but heavy pixelation often makes it hard to read.

Tasmania's (TAS) utility poles have something green wrapped around them. The same thing turns up on the Furneaux Islands and King Island.

Queensland's (QLD) utility poles sometimes have a round blue marker. Black-painted numbers and horizontal insulators tilted slightly upward are also characteristic of Queensland.

South Australia's (SA) utility poles look like they're sandwiched between boards.

The Northern Territory's (NT) utility poles are made of steel, with a distinctive ladder-like lattice.

In Western Australia, road signs use yellow posts.

If a sticker near a traffic signal box or sign reads "VicRoads," it may be Victoria.
