The first power station in Australia was built in Melbourne in 1880. The first city to receive electricity in Australia was Brisbane in 1882.

Efficiency here would be power out divided by power in. Energy out is 38,000 Joules. A joule is a watt X second. The toaster is on for 120 seconds. So that 316.66... watts power over the time period t(which doesn't matter). 316.66... watts/ 330 watts = 0.95959.... efficient or 96%.
No
