You have two options: Get it done privately and pay the costs upfront or have it done publically and go onto a waiting list. I believe the wating lists for public tubal ligation are up to a couple of years long atm because it is not classed as urgent surgery but it would be best to check what the individual wait times are like in your area. As for the hospital stay I believe it is an over nighter or two night stay at most as most of them are done laparoscopically nowadays so just a couple of tiny cuts. Medicare does have a rebate for the surgery part but if you went privately you would have a gap to pay on this plus the anaethetists fee and the cost of the hospital bed so maybe a coouple of thousand dollars to fork out.
