In the interests of equity can you please provide analysis of the actions of other state premiers in handling international quarantine? NSW is 1/3 of the population but providing 1/2 of the national quarantine facilities.
Proportion relative to population IMHO is not the relevant statistic, I believe it should be made in comparison to what the proportion of international arrivals were coming into Sydney airport before CV.
NSW prior to CV was taking 46 to 47% of all international arrivals. So 1/2 now is nothing special as it is half of a reduced number due to Melbourne not currently taking any.
Prior to Melbourne outbreak, NSW was taking a little over 30% of all international arrivals for hotel quarantine when travellers did not have to pay for their quarantine. Pre-covid NSW State Govt & Sydney Airport operator had laid out plans to increase the market share to low to mid 50s. Either way, 1/2 is close enough to the pre-covid figure of 46 to 47%.
The NSW Govt & Sydney Aiprort were happy enough to be taking the revenue in the good times, so it is not unreasonable to expect them to take their fair share in the bad. Prior to the Melbourne outbreak - NSW was not taking our fair share. If we had then the figure would have been closer to 800+ per day.
Other States
Initially the NT Govt took 100% of potential CV infected international travellers as that was where the Wuhan flights all went to. NSW (& other States) did not want them. Very shortly thereafter the NT Govt introduced pay-your-way as crafty operators figured it was much cheaper to fly to Darwin than Sydney, Brisbane, Melbourne or Adelaide.
Once that charge was introduced then the international arrivals into NT dropped 97% in the following 4 weeks. Flows into Qld and Melbourne skyrocketed, Sydney increased somewhat as did Adelaide & Perth.
In the period from end April to mid/late June - Victoria was taking around the same number of international arrivals as Sydney despite pre-covid Sydney having around 35-40% more international air arrivals. So NSW was under-accepting & Victoria was taking more than its share. Victoria was accepting the largest number of flights from India, all flights from Nepal where as Sydney was getting a large proportion of its arrivals from the US, South America & the UK.
Post Melbourne 2nd wave then all international arrivals into Melbourne were stopped. NSW cut the daily arrivals first on July 4th and then again on July 14th (I think it was) to the 350/day figure.
