“In November I spoke about some significant personal health challenges that would require an extended absence. That diagnosis or challenge was, and still is, leukemia,” Mr Tilley said.
“While my illness is incurable, it can be managed with specialist medical care and on the advice of my doctors I will return to work in May.
“Being told I had cancer was a massive shock, but in some way, I feel fortunate, I have met so many others with far greater challenges.
“I have also had the benefit of an incredible support network of family and friends. The office and my parliamentary colleagues have continued fighting for issues here in Benambra, and I’m indebted to them too.
“This has also been a chance to witness the dedication, professionalism and expertise of our border medical practitioners, from my own GP through to oncologists and the many people in between – nurses, radiographers and sometimes just the smile of the person on the reception desk.
“But my health battles have brought into focus the demands of a job representing an electorate of more than 10,000 square kilometres and more than 50,000 people.”
Mr Tilley ruled out a by-election and said he is committed to seeing his term through.
“I want to thank everyone who has reached out directly and those who have contacted the office in the past four months with messages of support. They were really important to me.
“Now it’s time to prepare for a return to work and the next three years,” he said.
