Replication would be one option.

If one site is in Aus and one is in US, will it have delay using replication?
Do I need to setup link between 2 sites?

Another option would be to use the Service Broker.

This isn't something that sql server is traditionally good at. At least in comparison to some different datastores I've used. There are products such as CouchDB that have merge / merge synchronization as key principals.

what kind of data needs synchronizing?
How much delay is acceptable for cross country / continent replication?
If you are storing session state or other key/value type information and need to synch that, then you may want to consider looking into a distributed key value store instead.

Have a look at RIAK Enterprise.

I love riak's scaling model and how it performs under failure conditions.
