It wouldn't be a good idea to post a wedding cake to Australia as it would most likely be ruined and not keep on the long journey. The cake could be ordered by you and delivered by a good bakery in Australia. The only cake that would travel well is fruit cake (which was very popular several years ago) but the more modern cakes of today are finer cakes and not as heavy. If you feel a fruit cake for the wedding would be appropriate and appreciated then make it up (soak it in brandy for at least 2 - 4 months ... the longer the better) then ship the cake over to Australia and have a bakery ice the wedding cake. Be sure to have a professional package the wedding cake for you so it will endure the journey.

No, jam on a cake board would not make a fruit cake go mouldy. Keeping the fruit cake too long in a place that is warm and moist makes it go mouldy. Fruit cake should be stored in a tin in a cool, dry, dark place or refrigerated. Soaking a fruit cake with rum, brandy or other liquor also prevents spoilage.
* It depends what type of cake your wedding cake is. Most cakes can be frozen. The traditional wedding cake was fruit cake soaked in Brandy and it could stay in the crock (no icing on it) for several months. For other cakes they can be frozen, but it's best to ask a baker how long one can freeze the cake if it's a white or chocolate cake or one with strawberries in it.

To infuse fruit with alcohol effectively, soak it for at least 24 hours but up to a few weeks for stronger flavor.
