Go outside on a windy night and push it over. Then it will have to be replaced.
There are dividing fence laws in each state that legislates to the 50-50 payment of fence replacement to the same specs and type of previous fence. Council should be able to help.. If not, try the citizens advice bureua.
Hvae you got insurance if it does get blown over in the wind. They will pay for it and request the insurance details of the neighbour so they claim half from them.
