Mortgage holders will be hoping for signs the Reserve Bank is at the end of its interest rate hiking cycle in the minutes from the last board meeting.

Australia's central bank opted to hike by 25 basis points at the June meeting, sending the cash rate above four per cent.

The RBA has lifted the official cash rate 12 times since May last year, choosing to hike at every meeting except April.

The board will next meet on July 4.

NAB markets economist Taylor Nugent said the June rise was likely a close call and exactly how finely balanced the decision was would be telling.

He hoped the minutes would reveal if the Reserve Bank board was really reacting to the incoming data on a month-by-month basis, or if it had instead lost confidence in returning inflation to target more gradually than some of its international peers.

NAB economists are anticipating two more 0.25 percentage point increases to take the cash rate to 4.6 per cent, with July and August the most likely months.

Two senior RBA officials will also make public appearances on Tuesday.

Key witnesses are yet to come forward to help find the person responsible for the brutal bashing death of a grandfather on a morning walk in Noosa.

Police have issued an appeal for public help a day after emergency crews found John Campbell Kerr unconscious with head injuries on a beachfront path in the Queensland holiday town.

Bystanders tried to help before paramedics arrived, but the 87-year-old died at the scene following the early morning attack.

A 27-year-old Gympie man was arrested about 100 metres away and charged with seriously assaulting a 69-year-old man on the tourist strip about the same time.

Detective Inspector Chris Toohey said Mr Kerr was a loving father and grandfather with nine grandchildren.

The former agricultural consultant was an avid golfer and had a lot of friends and associates in the community.

"We know there are witnesses that have not yet come forward," Det Insp Toohey said.

"And it is important for the investigation for Mr Kerr to speak with all persons who were present in and around Noosa Woods yesterday morning."

Det Insp Toohey said police were investigating the alleged assaults as separate incidents, but he added there was one known person of interest.

Mr Kerr and the 69-year-old man did not know each other and were not together at the time, Det Insp Toohey said.

There was no evidence of a weapon being used in either assault.

Officers want to hear from anyone who saw a man in various stages of undress anywhere near Hastings Street or walking into the Noosa Woods pathways between 5am and 7am on Sunday.

"One of our avenues is that the male person was naked at the time of the assault and in varying stages of undress," Det Insp Toohey said.

Police are still collating CCTV from the area but have no footage of either incident occurring.

Mr Kerr's family released a photo of him in the hope it would encourage more witnesses to come forward.

Det Insp Toohey said it was upsetting for members of the public to come across the seriously injured man.

"It's very confronting for the community that they came across that," he said.

"I will say, though, they attended to Mr Kerr extremely well and as a community we should thank them for their efforts."

The Greens and coalition have been labelled an "axis of evil" following their decision to block the government's multibillion dollar housing find for months.

Debate on the $10 billion Housing Australia Future Fund has been pushed until October following a Greens motion to delay talks, which the opposition backed.

The Greens, which have opposed the fund due to a lack of support for renters, said the delay would allow the prime minister to negotiate rent reforms with state and territory leaders at an upcoming national cabinet meeting.

The $10b fund would use investment returns to build 30,000 social and affordable homes each year for the next five years.

Trade Minister Don Farrell said the Greens teaming up with the opposition to delay debate on the fund was an "axis of evil" and warned the decision could lead to the government to consider it a trigger for a possible double-dissolution election.

"If this legislation was to have been in support, rather than be protested by the Greens political party today, we would already be on the way to resolving some of the issues which you pretend that you are interested in solving," he said.

"If the Senate defers bills to October, the government will regard this as the Senate failing to pass the bill and I'm sure you understand the consequences of that."

If the Senate twice blocks a bill, with an interval of three months in between, the constitution allows for a double-dissolution election to be called.

Constitutional experts consider a delay can amount to a bill failing to pass as it represents a form of blocking.

Prime Minister Anthony Albanese said the Greens had made themselves irrelevant in the housing debate.

"Those opposite have prioritised protesting, they have prioritised building up a profile, they have prioritised politics rather than prioritising building public housing," he told parliament.

"Building a (party) brand doesn't put a roof over anyone's head. Families can't take shelter under a petition."

But Greens leader Adam Bandt said it was on the government to act on rent reform if it wanted to get the housing fund over the line.

"It is up to Labor to now act on soaring rent rises because unlimited rent increases should be illegal ... people can't take any more," he told reporters in Canberra.

"We have bent over backwards - the response from Labor has been everything is impossible until they change their mind and we saw them change their mind over the weekend."

The government was hopeful of a breakthrough in negotiations on the housing bill after it announced a $2 billion commitment for social housing to be shared among the states and territories.

Mr Bandt rejected suggestions the delay could be used as part of a double-dissolution trigger.

Housing Minister Julie Collins said every six months the bill was delayed represented another $250 million that could have gone to building more homes.

"This government is being very serious about getting more homes on the ground and getting more Australians into safe, affordable homes," she told parliament.

"It's a shame we can't say the same about some of the other people in this place."

Greens housing spokesman Max Chandler-Mather said the government's announcement of additional funds showed action on rent reform was possible.

"We know pressure works and now we're going to exert that pressure to make sure that the one-third of this country who rents get the same thing that Labor did for energy bills," he said.
