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 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.
brown widow is a medium sized spider with a fury body and resembles the brown rucluse but has the black widow hour glass on the bottom of the abdomen <><><> Black widow- up to about the size of a large green pea. Round body, shiny black. The red hourglass marking is on the belly. Link below will take you to a photo showing markings.
A spider that is brown with a large yellow belly might be a brown widow. Almost all spiders roll into a ball for protection. This spider could also be a garden orb.
Depending on its size, the spider with tan and brown striped legs and a large white abdomen might be an orb weaver, a common house spider, or even an orchard spider. There are a huge variety of spiders with this description.

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.

The black hairy jumping spider has a black dot on it's head, and large green fangs. This spider is a beneficial spider, that keeps other insects at bay.

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.
