In Australia we also have https://staticice.com.au/ which lets you find stockists, and quickly compare prices for, any piece of IT gear. Sadly it doesn't include postage, which can add $20 onto even the smallest / cheapest bit of kit.

Plus we've got our own local version of https://au.pcpartpicker.com/ though I've had mixed success with that the past few years. Supply chains are still really screwy domestically.

There's a bunch of highly dubious vendors in AU, no one quite knows how they stay in business. Best bet is to search whirlpool.net.au for horror stories if you're about to make your first transaction with a new vendor.
