Both territories have been relatively predictable in the previous two elections.
However, as Amanda Cavill reports, this election could be a little different, particularly in the Senate.
The Northern Territory has just two federal members in the House of Representatives, representing the seats of Solomon and Lingiari.
The Solomon electorate includes the cities of Darwin and Palmerston, while the Lingiari electorate includes the rest of the NT, and the Indian Ocean territories of Christmas and Cocos-Keeling islands.
Over a quarter of the Northern Territory's population is Indigenous, and Indigenous groups have traditionally voted Labor.
Lingiari has been won by Labor at every election since it was created in 2001, while urban Solomon has tended to be a marginal Country Liberal Party seat.
Lingiari is held by the federal Minister for Indigenous, Rural and Regional Health, Warren Snowdon, and is held by a margin of just under four per cent.
Mr Snowden says he's hopeful of retaining his seat, and he thinks Labor could also win Solomon, currently held by the CLP's Natasha Griggs.
"I think people in Darwin in particular will be very concerned about what's coming out of the Northern Territory government. They increased power prices significantly, people know the cost of living is a real issue in Darwin and all the Northern Territory government has done is add to the cost of living. Frankly I think people are fed up. They're very concerned so I think there's every chance people will say 'look you know having Tony Abbott in Canberra and Adam Giles in Darwin what will that mean to us?'"
But it's the race for the Northern Territory's two Senate seats that are attracting more attention.
Unlike other Senators' seats, Territory Senators serve for the same term as members of the House of Representatives, so they become vacant at every election.
One seat is currently held by the Country-Liberal Party's Nigel Scullion, the other by Labor's Trish Crossin.
Senator Crossin had been hoping to stand again.
But former Prime Minister Julia Gillard announced in January that she was making a so-called ''captain's pick'' to install Indigenous candidate of Nova Peris at the top of the Labor Senate ticket.
Senator Scullion, who's seeking re-election for his party, says there could be a backlash against Ms Peris because of the way she was chosen by Labor.
"There's been an awful lot of concern from the Labor Party about the way under which my colleague Trish Crossin was ejected from the Senate. She had a career. But suddenly to be tapped on the shoulder and be told" by way you don't have a job any more" as of immediately. I think offended a lot of Territorians not only IN the Labor Party. They do the wrong thing by someone people remember."
The Greens are also vying for a Northern Territory Senate seat.
They've put forward their own Indigenous candidate, Warren H Williams.
Mr Williams says, if he is successful, his priorities would include trying to get parliament to reconsider the Northern Territory Intervention, as well as law enforcement and land tenure.
"First of all I would like to see someone coming up and having a look at the laws of the Intervention, because statistics that we get from down here are not the same things that's happening up there. I mean people keep saying that the intervention is working, stronger futures are working. But they're really not."
The Australian Capital Territory also has two seats in the House of Representatives.
They have always been held by the Labor Party, and don't appear likely to change hands this election either.
The ACT also has two in the Senate, and like in the NT, they become vacant at every election.
Labor traditionally garners the most votes in the Senate in the ACT, with the second quota of votes traditionally going to the Liberals.
But this year the second seat is being hotly contested.
For the first time in 10 years the Liberal Party's Gary Humphries will not be running for the Senate after he was toppled in a bitter pre-selection battle by the ACT's former opposition leader Zed Seselja.
Gary Humphries only very narrowly won the seat in the 2010 election, and polling shows Mr Seselja is not as popular, so he could have his work cut out to hold the seat for the Coalition.
But it's not at all assured that Labor would be the beneficiary of a Liberal loss.
In the green corner is Simon Sheikh, the former national director of the activist group, GetUp, who is now campaigning to win a senate seat for the Greens.
He says the Liberals' pre-selection fight, and the federal Coalition's promise of thousands of public service tax cuts, should be enough to keep the Senate seat from the Liberals.
"The polls all show that this is a very tight election race. Canberrans are walking away from Zed Seselja and the Liberal Party because they don't want to reward him from the way he treated Gary Humphries and they don't want to reward a party that's promising to hurt our community and our economy when it comes to job cuts."
Independent voluntary euthanasia campaigner Philip Nitchke is also standing.
Mr Nitchke says he believes he can win the seat, though not by a wide margin.
"In terms of how that's going to influence what actually happens in federal parliament that'll depend on how the election finally plays out It's likely I think with the recent developments it's possibly quite close. In fact it is going to be close, particularly in the Senate."
There are 27 Senate candidates in the ACT and 24 in the Northern Territory, many more than in previous years.
So while the Senate ballot paper won't be one-point-two metres long like the one in Victoria, voters have plenty of choice.
