AEMO Dashboard
The generation and import data are from AEMO’s dashboard (NEM Dispatch Overview tab)

We can see that in NSW at 14:30 EAST demand of 11,608 MW was higher than generation 9,987 + 486 = 10,473 MW, a deficit of 1,135 MW.
AEMO’s dashboard also shows demand curves and electricity spot prices in a moving window of 2 days, separate for each State:
