Hi Matt,
If you're in Australia that's different, expected delivery schedule is up to 10 days after subscribers here in the UK receive their copies, but Australian subscribers are advised to wait 14 days, making it around 1 week after the onsale date here in the UK. As the issue has just gone on sale today here, if your issue hasn't turned up by this time next week then it's time to start worrying
Thanks,
Amy
