Labor Leader Anthony Albanese was joined by the prime minister's wife and former Liberal prime minister Tony Abbott at a Good Friday mass in Sydney, while Scott Morrison attended a service in Melbourne.
Mr Morrison and Mr Albanese suspended political warfare for the day but both will be back on the hustings on Saturday for day six of the federal election campaign.
"Easter is not about politics. My faith isn't about politics," Mr Morrison said.
The prime minister spent the morning at a service at Syndal Baptist Church in Glen Waverley in Melbourne's west with Liberal MP Gladys Liu.
Ms Liu holds the seat of Chisholm by a slim margin of 0.5 per cent, and it's considered a key target for Labor at the May 21 poll.
Mr Albanese attended the Maronite Catholic mass at St Charbel's Monastery in Punchbowl in Sydney's west in the safe Labor seat of Watson held by frontbencher Tony Burke.
Mr Morrison's wife, Jenny, and their daughters, Abbey and Lily, were greeted by Mr Albanese, as was Mr Abbott. Mr Albanese and Mrs Morrison both gave readings.
Earlier, Mr Albanese and Mr Morrison posted Easter messages online saying it was a time for families to come together.
Elsewhere, three of the four police officers from the prime minister's security detail injured in a car crash in Tasmania on Thursday are out of hospital.
Two Tasmanian Police officers and one federal police officer have been discharged. A second federal officer is still being treated in hospital for his injuries.
Mr Morrison, who spoke to the two federal officers on Friday, said the incident was a reminder to stay safe on the roads this Easter.
"If you are travelling around of course, please be safe, be careful," he said.
The prime minister had cancelled a planned speech at a defence conference in Tasmania on Thursday afternoon after the two-car crash.
Mr Morrison wasn't involved in the crash - he was in a car moving ahead of the accident - and the driver of the other vehicle involved was unhurt. Tasmania Police are still investigating.
Meanwhile, government frontbenchers Stuart Robert and Simon Birmingham spent Friday trying to walk back the prime minister's apparent lack of enthusiasm for a federal anti-corruption watchdog after he backflipped on a promise to set it up after the 2019 poll.
Both said the coalition will have another go at trying to establish the watchdog if the government is returned.
"We will come back again and we will seek, through a bipartisan level, to get that going," Mr Robert told Nine Network.
Labor finance spokesperson Katy Gallagher clarified comments made by Mr Albanese earlier in the week when he said Labor's plan to set up urgent care clinics had been "fully costed" by the Parliamentary Budget Office.
Senator Gallagher tweeted late on Thursday that the policy "has not been formally costed by the PBO" and that the $135 million cost over four years was "based on work done by the PBO".
Mr Morrison and Mr Albanese will go head-to-head in their first debate of the election campaign on Wednesday in Brisbane ahead of the poll on May 21.
