in response to Ben Raue:

Update: The result today saw Scott Ludlam (GRN) and Wayne Dropulich (Sports Party) elected instead of the PUP and ALP candidates who had won in the first count. The margin at the key point is 12 votes, a net turn-around of 26 votes. The case seems set to head to the Court of Disputed Returns. […]

The dates for the by-elections haven’t been announced.

The earliest possible date for Griffith is February 8, if the by-election is called in the next week.

There has been speculation that Redcliffe will go on the same date, although it isn’t required. I don’t think as much time is required for the Redcliffe by-election.

The WA Senate by-election cannot begin until the Court of Disputed Returns considers the matter. Unlikely to be in February
