OP here, you are welcome. If I can help any teachers here, I will.

All private schools in OZNZ follow the Teacher's Collective(A set pay scale by the Ministry, that is also why you see teachers striking to demand more pay). You can find their pay scale on Google. There is no PB or thirteen month. After tax for a 10-year experienced teacher is about 6k NZD/AUD. Singapore teachers are still the highest paid in the world.

In NZ you need dual income as the standard of living is on par, except for cars. Auckland/Melb/Sydney has the highest rentals. Housing pricing is just slightly lower compared to SG (instead of 99 years, it is freehold, instead of apartments, it is townhouse or landed).

But the work-life balance is fantastic.
