Federal electorates in four different states will hold by-elections on the same day this weekend. And whilst those electorates are just five of the 150 seats in the lower house of federal parliament, the results of the voting could be felt far and wide across federal political scene.
The scandal involving the citizenship of many federal politicians has, at varying times, intrigued, disgusted, and bored Australians. The saga will come to what appears will be its final conclusion this Saturday.
Three Labor party members of parliament and from the Centre Alliance will try to win back the lower-house seats they had to resign due to being in breach of the now-infamous Section 44 of the Australian constitution, which bars dual citizens from sitting in federal parliament.
In addition, the seat of Perth will have a by-election, caused by the resignation of Labor M-P Tim Hammond, who has quit federal parliament to spend more time with his family.
Together, these five by-elections on the one day has this Saturday being dubbed by politics watchers as Super Saturday.
Now, not all the by-elections are shaping up as thrilling.
Mr Hammond's old seat of Perth is expected to be easily retained by Labor- the party's Western Australian state secretary, Patrick Gorman, is set to succeed him.
The nearby seat of Fremantle is also expected to be retained by Labor- Josh Wilson trying to regain the seat he won at the federal election in 2016, and then had to resign in May. The government isn't even running candidates in these two seats.
But in the other three seats, events promise to be a little more interesting.
In the electorate of Mayo, located to the east and south of Adelaide, Rebekah Sharkie of the Centre Alliance- Nick Xenophon's old party- is trying to win back the seat she won from the Liberal party at the 2016 federal poll. Trying to win it back the seat for the Liberals is Georgina Downer.
It's the seat her father, former Liberal party leader and Foreign Affairs Minister, Alexander Downer, held for twenty-four years.
But the battle in Mayo- and its implications- pales in comparison to what's going on in two electorates- one in Queensland, the other In Tasmania.
The electorate of Braddon occupies most of the rural north-west and west Tasmania. It was won by the Labor party candidate, Justine Keay ((key)), at the last federal election. That ended the one-term reign of the former member, the Liberal party's Brett Whiteley.
But Mr Whiteley is a strong chance of winning the seat back. And that could mean trouble for Opposition Leader Bill Shorten, with a federal government not having won a seat in a by-election since 1920.
Prime Minister Malcolm Turnbull is ready to swoop on his seemingly teetering rival.
"The voters in Braddon know that a vote for Justine Keay is a vote for Justine Keay is a vote for Bill Shorten and his higher taxes. So, that is really the test. This is what this is about."
The chance for the major parties to gain an edge over their rival sending big personalities from both the government and the oppostion to a regional area of Australia's smallest state in droves.
That's to the amusement, and occasional astonishment, of some Tasmanians, such as former senator Jacqui Lambie.
Mate, I can tell you, us in Braddon, we're all bitching about having a by-election, but, by God, it's the gift that keeps on giving! It makes me sick, the amount of money that is going around. It's amazing how much money they'll spend on a seat to bloody win the damn thing, mate.
It's much the same in the division of Longman, north of Brisbane.
Polls suggest that Labor, and candidate Susan Lamb, who's trying to win back the seat, may narrowly lose the seat.
A loss in one of or both of Braddon or Longman would strengthen the case for Labor frontbencher Anthony Albanese to replace Mr Shorten as Opposition Leader.
Mr Albanese is insisting- publically, at least- that he's loyal to Mr Shorten.
Campaigning in Western Australia, Anthony Albanese is trying to put the pressure back on the government, concentrating on the areas in Western Australia where Labor is likely to win, rather than the likely closer results on the east coast.
These by-elections are a critical test for Malcolm Turnbull, and he's already failed in Western Australia, by failing to be even in the field in Perth and in Fremantle. That's typcial of the contempt that we've seen from the federal coalition towards Western Australia.
A good result for the government - and a poor one for Labor - in the by-elections could even hasten the next federal election, which is due by May 2019 at the latest.
And Labor is under renewed pressure just days out from the Super Saturday by-elections, with new internal polling showing the Liberals taking the lead in the Tasmanian seat of Braddon.
The Liberal Party poll of 500 voters, published by the Seven Network, puts the government ahead of the opposition for the first time in Braddon, by 51 to 49.
But separate Labor polling suggests its candidate Justine Keay is favoured by 47 per cent of respondents, ahead of the Liberals' Brett Whiteley on 37 per cent.
Polls are also pointing to the South Australian seat of Mayo being retained by the Centre Alliance's Rebekha Sharkie.
