I just wanted to take his place,” she said.“Mullaloo is apparently very well known for the fact that it is got really shallow parts in it, and Scarborough is the same.”She called for others to be careful when swimming and to make sure it was safe before diving in.Matthew, who had just started an apprenticeship with Western Power, remains in intensive care at Royal Perth Hospital and will not have surgery straight away, with doctors allowing time for the swelling to go down.
