We're not the only country with a by-election or two.
In Australia voting is taking place in the Gippsland seat in rural Victoria. It's been held by the National Party and its predecessors since 1922.
Labor are unlikely to gain it but might get a swing in their favour in the first federal by-election since Kevin Rudd took power.
Result after transfers in the 2007 General Election was Nat 55.9%, ALP 44.1%.
ABC's News' Antony Green's profile of the seat is here.
If anyone in Australia is reading this and knows the result before I post it here, please can they post it in the comments.
