An arm and a leg. Lol. Check out the Aus post website, it may have an estimate on there.

I could be wrong but I think they have prepaid satchels for overseas. Not sure on the price though sorry.

$20 – $30 as it generally goes on the weight and not on size of the package.

I think Aus post has information on their website

I’d say about $20, go on the Aus post website

Hope you managed to organise your parcel.

Thanks for your help everyone

Yes Australia post have a calculator on their site now which is great but just as easy to pop in to the post office

For a parcel up to 1kg it will cost between $19.90 and $97.95
Australia post has a calculator on their website that is up to date and easy to use.

In my experience using Australia Post, you could pay $20-30 to send 1 kg.
