The skinny: we're having our wedding in Australia (we're in Canada). We only want to invite the groom's immediate family from Canada - that is - siblings + parents. The rest will be family/friends of the bride in/from Australia.
The problem: Groom's parents want the aunts/uncles invited as a 'gesture' banking on them not actually making the long trip. We don't want to invite them at the risk of them actually showing up. We simply can't afford to have them there and don't want to offend cousins, friends, etc. by just inviting aunts/uncles. At the same time, we don't want to offend them by not sending them an invitation.
The compromise(?): My idea is to send a wedding 'announcement' to those who we cannot afford to invite instead of an invitation. Is this acceptable?
The ask: Please, please, please help us with some advice on how to handle this
