Molly star Samuel Johnson put his acting career on hold in February to help his terminally ill sister Connie in her efforts to raise money for cancer research.
Nine months later, her health is taking a turn for the worse and the pair are hoping to pick up the pace by breaking a world record.
Setting their sights on the longest line of coins, Samuel and Connie announced the project via their Love Your Sister Facebook page last week with the target of collecting 4 million 5 cent pieces - the equivalent of close to $200,000 - to beat the current Guinness record of 75.4kms held by a town in Austria.
However in just 24 hours, they had already amassed 3.2 million coins, which jumped to 5.2 million at the beginning of this week, bringing their total length well clear of the standing record at 102kms.
Connie’s response was to write, “It's possible that I am not only the happiest cancer patient in the country right now, but that I am the happiest person, full stop.”
Having originally planned to launch the initiative next year, a recent doctor’s appointment revealing that Connie’s cancer has spread to her liver has made them fast track their efforts. They now intend on laying the coins in a heart formation this coming Valentine’s Day as February coincides with the anniversary of the decimal system.
To help achieve the mammoth feat, Samuel and Connie have teamed up with the Royal Australian Mint, Questacon and The National Institute of Measurement.
Of course this isn’t the first time the family have tried their hand at a world record, after Samuel unicycled around Australia back in 2014, raising $1.75 million for the charity in the process.
Seven months later, he announced via social media that he would be quitting acting to focus more fully on his fund raising efforts.
“Cancer is the last true riddle of our time (not of our doing) and I wanna be part of the push to solve it once and for all — part of the new 'moonshot',” he said at the time.
Connie has been battling cancer since she was first diagnosed with a bone tumour at age 11. Just over a decade later it returned in her womb and at 33 she was diagnosed with breast cancer.
