Population of Canada -- 37.6 million (source: Canada, Demographic Indicators

population of Australia -- 25.2 million (source: 3101.0 - Australian Demographic Statistics, Jun 2019 )
37.6/25.2 = 1.49 (close enough to 1.5 ??)
I'll accept your figures for infection rates because
1. the number of Canadians testing positive has increased very materially in the last 24 hours, and
2. I haven't seen the latest figures for Australia as it's still early Sunday morning in Perth, and
3. currently there's a PLUS 17 hour time difference between Sydney and where I live in Alberta meaning that with the rapid change in the number of confirmed COVID-19 infections comparison of infection rates are more than a bit rubbery.
The point I was trying to convey was that in Canada the restrictions on travel (essentially don't travel outside the country) and limits on venue size (maximum of 250 people) compare less than favourably with those currently in place for Australia (venue size limit of 500 doesn't start till Monday) and overseas travel is still mostly OK.
I was at my local nordic centre this morning (Saturday) and while the place was fully staffed and the maintenance staff were working outside, the place was fully taped off because it can accommodate more than 250 people. although the corridors, toilets and cafeteria (limit to 3 people at a time) were still functioning the centre looked like a ghost town.
