It wont be thrown out it will be amended. The constitutionalise any other law evolves. They will remove reference to the queen, if that is what the referendum approves and insert another term such as president etc.
It will not change the land ownership. It will simply be in the name of the Australian Government if the crown is removed. Nothing will change there.
The crown will be replaced with an alternative and all things will remain the same.
In 1975 the Australia act signed between Australia and Britain ended the money we pay to the UK.
In order for the constitution to be changed they need a majority of states and a majority in each state.
If both do not happen it will not be changed.
There have been 44 referendums held since 1901 and only eight of these have been successful. The most successful referendum in Australia's history was in 1967 where 90.77% of the nation voted 'Yes for Aborigines'.
Here are the referenda that ere held and what the figures were
I would not concern yourself too much about changes. The last time they tried to remove the queen it failed.
I hope this makes sense and is of assistance. If there is nothing further
