Looking through https://www.acgov.org/rovresults/rcv/248/ https://www.acgov.org/rovresults/rcv/248/ the largest RCV race was for Oakland mayor, with ~125k votes. Most races had <20k votes. An Australian lower house district averages ~105k votes, the largest has ~118k. Per https://www.acgov.org/rovresults/248/ https://www.acgov.org/rovresults/248/ the largest, non-RCV races (eg Attorney-General) had ~430k votes which still seems doable given the process is O(n). What I didn't account for in my response is the sheer number of positions voted for in a single election. An Australian voter typically votes for two things - House and Senate - and occasionally a single ballot measure on top. Australian Senate races are both more complicated (proportional representation) and cover much larger districts (New South Wales has ~5.4M voters). It can take weeks to declare the result, which is definitely a downside. https://www.aec.gov.au/voting/counting/files/senate-count-process.pdf https://www.aec.gov.au/voting/counting/files/senate-count-pr...
