DANIEL Morcombe has one million friends and supporters he will never meet.
One million school students and many thousands of other supporters are expected to take part in tomorrow's Day for Daniel.
Flashing traffic signs, a larger finishing point and bus transfers have all been organised for what is expected to be a record crowd at the Walk for Daniel tomorrow morning.
"It's a bit unknown - we're sort of catering for 2500 to 5000 people," Denise Morcombe said.
Her husband, Bruce, said the participation in the seventh annual Day for Daniel was "a phenomenon".
With upwards of 2000 schools and organisations registered to take part in the national event, Mr and Mrs Morcombe said yesterday they wanted it to be a day of action and not a time to mourn.
"It's pretty massive. It's pretty awesome," Mrs Morcombe said.
"Our aim when we first started was to go national. And that's happened, so it's pretty good."
Last year's walk was the largest since its inception in 2005, with about 1000 people joining the procession from Daniel's old school to the Palmwoods football fields.
The Daniel Morcombe Foundation has posted 6000 child safety DVDs to schools over the past two months.
There have been orders of several thousand T-shirts and the foundation ordered an extra 50,000 wristbands.
They have run out of bunting, flags and balloons in preparation for the day.
"I think the work that we've done over the previous five years has got us to where we are today," Mr Morcombe said.
"But certainly the arrest on August 13 (of a man charged with Daniel's murder) has been a significant event in capturing the Australian public's attention.
"Child safety is important and what happened to Daniel is terrible,'' Mr Morecombe said.
"We're going to make a difference and I think everybody's standing up to say, 'I'm going to join the Morcombes in their fight to make sure our kids are safe'."
There are more than 20 different walks across Australia.
Mr and Mrs Morcombe will take part in the Sunshine Coast walk tomorrow, one on the Gold Coast on Saturday, one in Brisbane on Sunday and another in Melbourne a week later. "We'll be fit by the end of it," Mr Morcombe said.
Schools participating in the Day for Daniel will have lessons about child safety during the day.
"Day for Daniel is what we call our day for action," Mrs Morcombe said.
"We want our kids to come home safer in the afternoon than when they left in the morning."
