Australian grandmother Irene Keel continues to wait for suitable conditions in her quest to become the oldest person to swim across the English Channel.

Australian grandmother Irene Keel’s bid to become the oldest person to swim across the English Channel is being delayed by bad weather.

The 73-year-old Queenslander has been in Dover since last week but her wait for suitable conditions to tackle the 34km swim from England to France goes on.

Ongoing rough conditions in the Channel mean Keel is unlikely to attempt the swim until this weekend at the earliest.

The grandmother of three said last week she wanted to swim on a neap, rather than a spring, tide.

“It’s a waiting game and you have to have patience,” she said.

“If you haven’t, then it starts playing with your head and that’s no good.

“I’m here in England until September 5 so hopefully somewhere in that time, on a neap tide, I will have a nice day.”

If Keel does complete the swim she’ll seize the age record from Bondi lifesaver Cyril Baldock, who only claimed the title last week.

The 70-year-old NSW grandfather made history in 12 hours and 45 minutes.

Keel is undertaking the swim to raise money and awareness for Motor Neurone Disease.

Conditions have not prevented another Australian tackling the Channel, with triathlete John van Wisse attempting the cross on Wednesday as part of his ultra-triathlon from London to Paris.
