Mr Spencer came down from the tower after midday on Wednesday, ending a long-running protest he's had over laws that prevent him clearing vegetation on his property not far from Cooma.
He's been calling for a royal commission into the laws and says other farmers are experiencing the same hurdles because of the laws.
He was lowered to the ground with the help of his son, 33-year-old Aaron Spencer.
"I was pleased to see that so many people were becoming aware of Australian issues," the grazier told reporters, shortly after he arrived on the ground, weak and unable to move.
"What I really want to get home to people is this country is worth it."
Mr Spencer then broke down into tears, before continuing.
"We have to get our country back in the hands of the people, it's the people's nation and that's what always made this such a wonderful place and to somehow, over the last 50 odd years... they've taken it from us."
Asked how he'll fight on the ground, he said "I haven't got that far in my thoughts yet, I've only been here for three minutes."
However he then said "let me tell you, if they thought I was tough up there, wait `til they see me get my strength. I'll be a pain in their side, I can assure you."
After being told opposition leader Tony Abbott had thrown his support behind him, Mr Spencer couldn't believe it.
Earlier on Wednesday morning, Nationals senator Barnaby Joyce said he would push to have Mr Spencer come to Canberra for a rally when parliament resumes, a move the grazier said he would probably agree to.
After he was lowered, the grazier was helped into a four-wheel drive and driven back to his property before being taken to Cooma Base Hospital.
Mr Spencer's plight has grabbed nationwide attention, including that of the federal opposition.
"I think he's certainly highlighted the failures of the Labor government both here in NSW and federally to deal with this issue," Tony Abbott said.
Mr Spencer's protest was an important point that needed to be made, the opposition leader said.
Nationals senator Barnaby Joyce said the last thing that the public wanted was for any harm to come to Mr Spencer.
"We can continue this fight for property rights that have been taken off so many people because of these crazy environmental laws," Senator Joyce said.
The federal government was also relieved the 61-year-old decided to end his hunger strike.
Climate Change Minister Penny Wong said the government remained open to meeting with Mr Spencer.
"Mr Spencer has certainly made his point very clear.
"We're very pleased that, given the concerns for his health, that he's made this decision."
The NSW Farmers' Association, while also glad that Mr Spencer ended his hunger strike, said it would continue to fight on his behalf.
Association president Charles Armstrong said the lobby group understood the frustration many farmers felt over governments' ill-considered decisions relating to what can or can't be done with their land.
"This is an issue that the association has worked long and hard on, and one that we are committed to for as long as it takes to see real change," Mr Armstrong said.
Mr Spencer will remain at the emergency department of the Cooma Base Hospital overnight, under supervision.
