Not really, but it's alternating between pissing down and being humid. Typical Melbourne weather, then.
Selling on ebay is easy as pie. Just ensure that you can get the goods out in a timely fashion once you sell and that you make the payer pay for postage. I find it's only really worth selling big items as the time and hassle required to get down to the post office and get a parcel isn't worth it.
Some tips with listing:
Don't list multiple items in one auction. Ie, if you have 5 PS2 controllers, sell them seperately and offer the buyer savings on postage if he buys from your other items ( provide link)
Give all relevant information about product and include in your terms the right to withdraw auction from sale at any time.
Other than that, just follow what most other successfull sellers do (ie. include a pic, although you do have to pay) and give prompt responses to potential buyers.
