WHAT THEY HAD TO DEFEND

Why neither leader attended a repatriation ceremony for Australian war dead in Sydney on Thursday.

WHAT MADE NEWS

* Turnbull reveals his father-in-law has apologised to Tony Abbott for calling the former prime minister a "lunatic".

* Shorten is under pressure over his stance on business tax, as Malcolm Turnbull came to the rescue of a former minister facing the loss of his seat.

* Independent senator Nick Xenophon has commissioned an audit of his financial affairs after admitting he "stuffed up" by failing to declare his directorship of a company run by his father.

* PM reinforces the government's determination to push ahead with a crackdown on superannuation tax concessions, describing it as "absolutely iron clad".

* New polling shows cabinet minister Christopher Pyne in Sturt and another Liberal MP - Jamie Briggs in Mayo - are battling to hang onto their SA seats.

* Former ALP national president Warren Mundine criticises Labor for its "anti-business rhetoric".

* Labor is furious with the ABC over its Vote Compass website, arguing it misrepresents the ALP's position on election-deciding policies including penalty rates and boat turn-backs.

THE POLLS

The latest Seven-Reachtel poll has the parties locked at 50-50, a week after it had Labor leading the coalition 52-48 per cent.

THEY SAID WHAT?

"To elect Abbott in his place is the equivalent of putting the bull in charge of the china shop or the principal lunatic in charge of the asylum."

- Tom Hughes, the PM's father-in-law, in a letter to his brother in 2009.

TWEETED:

"Don't fall for the illusion Turnbull is different to Abbott - he is Abbott 2.0."
