Perhaps the max of 6 tests in a home summer should be reviewed. 7 or 8 is fine, England sometimes have 11 tests at home period.The Ashes has been good recently because the teams have been evenly matched but it was ******* boring for about 25 years before that.
Half the reason we dominate home series is that many teams hardly ever visit. If Sri Lanka and Pakistan (let alone Bangladesh, who we actively try to avoid) were here more often and had a chance to get more familiar with the conditions, the cricket would eventually get better.
Very short-term thinking to have the same few teams play each other again and again.
This season is clearly different due to Covid, but assuming it's a normal year, what's wrong with 4 tests vs India, then 3 vs a Pakistan - Sri Lanka - WI et al in places like Tasmania, Canberra, WACA or Metricon - the pitches have been half decent with the BBL. It'd give them a little more exposure here and bringing the game to smaller venues should still be somewhat profitible.
I can see Tasmania supporting test cricket regardless of who Aus is playing, for example. GC is a bit fair-weather though tbf.
