Which companies in Australia have prepaid cards? What are the packages for cards with traffic? How many minutes does it take for each Australian domestic call to return to China? ...

Prepaid: Call Australia: 3 and Vodafone: (Now a company, 3 was acquired) The signal is average, but because many people use 3 and Vodafone and talk to each other for free, it is still worth comparing.

Telstra: Relatively expensive. Because the signal is the best, it is equivalent to domestic mobile.

Lebala: 0. 15 per minute (both in Australia), and text messages 0. 15 per minute.

Call back to China: Harochina, yes, but the signal is very poor. I often hear people calling over the line. The cheapest, a few cents a minute, seems to be fifty cents.

I use daybreak, 300 minutes 10 yuan. I seem to have forgotten. The signal is good. Call from home landline, 50 cents at a time (seemingly)

These two cards are not sim cards. I think it's more expensive to use sim card.
