The annual McHappy Day returns to Mandurah on Saturday.
This year's aim is to raise $5 million nation-wide to support seriously-ill children and their families at a time they most need it.
The funds will go towards programs including the Ronald McDonald House, the Ronald McDonald Learning Program, Ronald McDonald Family Rooms and Ronald McDonald Family Retreats.
This year's fundraising goal would equate to supporting families in need for more than 31,250 days.
Locals can help out by buying a Big Mac, a pair of limited edition Silly Socks or donate online.
Since 1981 the Ronald McDonald Houses have collectively housed over 3.4 million nightly guests and this number is set to grow with demand from families increasing.
Most families who stay at a Ronald McDonald House are from regional areas and would otherwise have nowhere to stay while their child is in hospital.
By becoming a local community supporter and participating in McHappy Day, you will help to keep seriously-ill children close to their families when it’s needed most.
