By the way, don't let any postal official tell you that they 'don't sell IRCs'. This isn't true - the UPU says that 'Great Britain' does.

If you want some Aus stamps, I am sure some users here will sell/trade some

They are available so ask somewhere to order some for you or try somewhere else. I just walk into my biggest one and they keep them in the stamp book.

I have tried several BIG post offices and we cant get IRC here

UK stamps will not work. For International postage you need International Reply Coupons, price £1.40 available at larger Post Offices. The good news is IRC'S in Australia have a high value so you will only need to send one (as long as return contents do not weigh more than 50g).

It all depends on the weight of your envelope. Weigh the contents you expect to receive back and then go onto the australia post website and pick international letters, then choose destination (UK) and put in weight and it will tell you how much it will cost and you can work out stamps from there.

Can anyone help me.
I want to write to a couple off celebrities who live in Australia. Now what Stamps will i need for a Stamped Addressed Envelope so they can reply back to me i live in the UK

Thanks
