Western Australia only played 4 matches between 1947/48 and 1953/54.
This was a "probationary" period for them, and to compensate for having played 3 less matches than the other 4 states, the points for all states were worked out on a percentage basis - (points/possible points)*100
I don't know why the 1954/55 season had teams only playing each other once (and WA just two matches), but in 1955/56, WA had their first full home and away program.
Tasmania only played 5 matches per season between 1977/78 and 1981/82. Again, this was a "probationary" period for them, but this time to compensate less matches than the other 5 states, their points was multiplied by 9 and divided by 5.
Final at the end of the home and away season first implemented in 1982/83.
Tasmanias' first season of a full home and away program was in 1982/83.
