If you are in Australia it sounds like a Mouse spider. I'm in North America and found a similar spider in my basement this morning, but can't seem to find out what it is.
It is likely a brown widow spider. They're not as venomous as a black widow spider, but you should still be very careful with it.
It sounds like you are describing a Woodlouse Spider (Dysdera crocata). These spiders are brown with a distinctive large yellow or orange abdomen, and they are known for their behavior of rolling into a ball when threatened for protection.
It depends on what species you desire, and what you consider huge. In my opinion the male Hobo Spider has a pretty large abdomen. However when comparing most male spider's abdomen to the female abdomen, the answer might as well be no.
A black widow spider is black with a red hourglass shape on its abdomen, although the coloration can vary. Females are larger than males, with a body length of about 1.5 inches. They are known for their venomous bite.
If the stripe is rather large and the abdomen is longer rather than spherical, it's probably an Ant Mimic Spider (in the family Clubionidae, genus Castianeira). And it's harmless. If the spider is super shiny and has a very round abdomen, then it's probably some sort of widow and you should stay away.

The distinguishing features that can help identify a small brown spider with a large abdomen are its size, color, and the prominent size of its abdomen compared to its body.

In Kentucky, common spiders include the black widow, brown recluse, and wolf spider. Black widows are shiny black with a red hourglass shape on their abdomen. Brown recluses are light brown with a violin-shaped mark on their back. Wolf spiders are large and hairy with distinct eye patterns. It's important to be cautious around these spiders as some can be venomous.

In Idaho, common spiders include the hobo spider, black widow, and wolf spider. To identify them, look at their size, color, and markings. Hobo spiders are brown with chevron markings, black widows are black with a red hourglass on their abdomen, and wolf spiders are large and hairy. Be cautious and avoid touching any spiders you are unsure of.

Gasteracantha elipsoides is somewhat close to your description, but I'm not sure if it is the same. Gasteracantha elipsoides usually has six spikes, usually reddish.
