Newspaper headlines: 'Great train robbery' and crisps crackdown
The deaths of the British chief executive Richard Cousins and four members of his family in the seaplane accident in Sydney are widely covered - on the front and inside pages.
The Daily Mail has pictures of Mr Cousins' fiance, Emma Bowden, and her daughter, Heather, alongside the headline: "Heartbreaking story behind seaplane crash that wiped out millionaire and his family."
The Sun says Mr Cousins lost his wife, Caroline, to cancer in 2015, but found love again with Ms Bowden.
Guests received their invitations for the pair's planned wedding just four days ago, it says.
According to the Daily Telegraph, Australia was the obvious choice for a family holiday to celebrate the festive season because Mr Cousins was a passionate cricket fan and wanted to take in a couple of Ashes tests.
The biggest rail fare increases in five years make the lead for two of the papers.
The i newspaper has the headline: "Great train robbery".
It says rail commuters have complained they are being penalised while motorists enjoy the seventh year of frozen fuel duty.
The Telegraph says it understands Transport Secretary Chris Grayling has asked officials to produce plans to peg future increases to the lower Consumer Prices Index measure of inflation to ease the burden on passengers.
A government source tells the paper: "The people who are paying these higher rail fares are the backbone of the economy.
"They are hard-working commuters, slogging their guts out day in, day out. They are the people we should be working to take care of."
According to the Daily Mail's main story, firefighters with just six days of first aid training are being dispatched to medical emergencies.
Crews in England are reported to have dealt with 44,000 call-outs last year that would normally have gone to paramedics - four times as many as in 2010.
It says fire brigades are stepping in because of a surge in demand caused by the ageing population and difficulties in making GP appointments.
Ambulance services are also struggling to recruit paramedics, the paper adds.
At the same time, calls to the fire service have fallen because of major advances in prevention and safety.
For its lead, the Times has a warning from the chief nursing officer for England that missed hospital appointments are costing the NHS almost £1bn a year.
It says Jane Cummings has called for the public to be more responsible about wasting time and resources.
The paper quotes her as saying a million more cataract operations or 250,000 hip replacements could be funded if the NHS didn't have to pay for appointments that people failed to attend.
Official figures show that nearly eight million appointments were missed in 2016-17.
The Mirror and the Sun both lead on the launch of the new campaign by Public Health England to cut down on sugary snacks.
It recommends parents should give their children no more than two snacks a day of 100 calories a time.
Under the headline "Mars barmy", the Sun says children are being banned from eating chocolate bars.
It says rationing treats so children can't even eat half a 230-calorie Mars bar isn't practical - and suggests they should get exercising.
The Mirror's headline is: "Stop your kids from eating crisps".
