That is ratings at nightime on January 25 for free to air channels as a share of viewing audience.

I'll translate
ABC has a rating of 13.7
Seven had ratings of 26.5
Nine had ratings of 27.7
Ten had ratings of 24.0
SBS had ratings of 8.0

ABC has more funding than any others and much less audience share. Of course this is a overall audience that is diminishing due to subscription channels and streaming.

Why pay so much for something so biased and irrelevant!
