Connie Johnson, the founder of cancer charity Love Your Sister, has died.

Her brother, Gold Logie winning actor Samuel Johnson, announced his sister's death on the Love Your Sister Facebook page on Friday night. The 40-year-old decided to end all treatment in April.

"It was so beautiful. We laughed, we cried, we sang stupid songs from our childhood to her, which she loved (mostly!)," Samuel Johnson wrote.

"I read her so many village messages, which she relished. She went so richly, and with such grace. Trust me, she was genuinely cushioned by your love, till the end."

Governor-General Sir Peter Cosgrove visited Connie at a Canberra hospice on Thursday, awarding her a Medal of the Order of Australia in recognition of her work for others battling breast cancer.

Diagnosed with terminal breast cancer in 2009, Connie launched Love Your Sister in 2012 to help raise funds for cancer research.

"Thanks for showing me that life is what we make it to be," Samuel Johnson said in a letter on the Love Your Sister site in June.

"Thanks for teaching me that now can still be awesome, even when you've so nearly run out of now and have no more real awesome left.

"I wish I could soften your pain, or lessen your fear, or give you something tangible, but tangible clearly isn't in season.

"I'm proud to walk you to the hardest part of the road. The end."
