The heartbroken friend of an English backpacker and his French companion who disappeared on an Australian beach has begged anybody with information about the pair to come forward.
Caraa Blackburn and Emily Powell were supposed to meet up with Hugo Palmer and Erwan Ferrieux, both 20, for the trip of a lifetime later this week.
Police said the British girls were in Sydney when the men went missing, but almost immediately drove to Port Macquarie in northern NSW to help with the search.

‘The day is finally here that I’ll be travelling to the other side of the world with my amazing friends,’ he wrote on the day he departed Britain, before tagging the trio.
‘Can’t wait to make some great memories and I couldn’t do it without you guys.’
Police on Tuesday night admitted Mr Palmer and Mr Ferrieux had most likely drowned due to the conditions, but had newfound hope on Wednesday morning.
‘From some of the discussions we’ve had this morning, we honestly believe that these people could well be alive,’ Inspector Neville said.
‘At this point in time we have not put a time frame on the search, our efforts are entirely to locate these two men.’

However, the air and sea search will be scaled back on Thursday based on ‘advice from experts’, but continue on the foreshore and coastline.
Police found the same car the men had purchased for their trip around Australia abandoned near Shelly Beach on Sunday.
Property belonging to the men was found at the beach by morning walkers at about 6.30am on Monday, but the two tourists have not been found.
By the time the search ended for the night on Tuesday, authorities had grown increasingly worried the duo, who are believed to have been swimming, may have drowned.
