Not much to negative gear. Most owned outright and paying ridiculous amounts of tax for my hard work.
Might be worth considering a Family Trust structure for any future investments. The benefits are all assets are held inside the trust with the income then being distributed to either yourself or wife depending on the most tax effective method. Whilst this may not help at the moment with the residency situation its good to establish early in case your situation changes. If your wife does become an Australian tax resident you can then send income to her without triggering any capital gains tax or stamp duties. It can then mean income can also be sent to your daughter once she turns 18 (albiet a long way down the track).
This just gives you maximum flexibility for minimal additional cost. There are numerous tricks and subtleties involved in this so definatly talk to your accountant.
