Sod the last post - just found a better way to get the cheapest calls to australia

Call Australia for only 2p/min from a landline phone! If you use briing.com's instant caller number it only costs 2p/min for landline-to-landline calls, so you can chat away for hours and save up to 28p/min over BT's standard rates!!

If you are a user of a T-Mobile phone (either contract or payg), you can also call Australia cheaply using briing.com - only 3p/min from your mobile to an Australian landline, and only 10p a minute mobile-to-mobile!
