Meet The Press screens at 1030am Sunday on Network Ten

AS more details emerge about the men that carried out this week's bombings in Boston, Network Ten's Meet the Press will talk to Attorney-General Mark Dreyfus about Australia's preparedness for a similar attack.

In the wake of the blasts which killed three people and injured nearly 200 on Tuesday, Mr Dreyfus insisted there was a constant threat of "violent activities'' on home soil but that Australian counter-terrorism organisations remained vigilant.

The Attorney-General will also face questions on the government's stance on same-sex marriage after New Zealand legalised the practice this week.

Opposition Leader Tony Abbott on Friday indicated he could be prepared to allow his MPs a conscience vote on the issue in the next parliament if that's what the party wants.

Meet The Press, which airs at 10:30am Sunday on Network Ten, will also look at the issue of immunisation with the Australian Medical Association President, Dr Steve Hambleton appearing as a guest.

Dr Hambleton this week warned the that the H3N2 influenza virus that killed 20 children in the US was heading to Australia and those who weren't vaccinated could die.

"It's absolutely true (that it is a killer flu), and some of the people reading this might be the victims, I'm sorry to say. It will kill people,'' he said.

As Australian's prepare to mark Anzac Day, Meet the Press will also examine whether troops returning from conflicts in Afghanistan and Iraq are being forgotten.

Dr Andrew Khoo from Brisbane's Toowong Private Hospital and David Catteral from the Federation of Totally and Permanently Incapacitated Ex Servicemen and Women will join the program to look at the issues faced by returning service personnel.
