It's way, way better than it was 15 years ago. Amazon and Amazon AU, Costco, etc. TradeMe for the cheaper stuff you don't want to wait for shipping from China.
But yeah the selection and availability is nowhere near the USA or even say.. Indonesia.
Indonesian here, electronics are everywhere yeah, especially Chinese-made. But the law leans a lot on protectionism, if you try importing one you'll be subject to 10% tax on customs and "other fees".
If you try to import a phone, you'll also have to pay additional fees to "activate" the IMEI, otherwise you won't be able to connect to local cellular providers.
It's lovely here, but it's been a real shift vs having nearly every retailer available in my county and being able to go to NYC for a weekend on a whim.
