Aussie here. Gumtree is worse than useless ever since eBay purchased it and ran it into the ground with ads, excessive sponsored placements, a substantial price increase for promotion, and did nothing about the rampant bot problem. You’ll occasionally get some use out of it, but imo, the site is dead, and by design. I truly believe eBay fucked it on purpose, as it used to be a decent competitor before the acquisition.
