"I think we made the right call by withholding things from them. In real life, of course all of us would have helped them out, no question about it.
"It's about separating Survivor from real life and putting on your game face."
Quinlan said he found the attitude change "easy".
"I think every last guy on our tribe is a gentleman and we understand the concept of being kind and being chivalrous. Everyone recognised that we had to act differently to be competitive.
"It makes perfect sense, it still does. Those woman understand why we're doing what we're doing. They're in no rush to give us their boat either because they don't want us to catch more fish."
Quinlan said his tribe mates underestimated the abilities of Colton Cumbie after he spent the first few episodes hanging out with the girls and securing an immunity idol. He now seems to be leading the tribe's biggest alliance.
"Initially Colton was just annoying everyone and he wasn't much of a threat. But once he got that idol on day three, everything changed. He decided that he wanted to be the shot caller.
"He really is an alpha male, he wants to control things, he wanted to be the leader of an alliance. He's in a pretty good spot and seems to know what he's doing."
Quinlan believed he was eliminated because this season's Survivor challenges were puzzle- and stamina-based, meaning his strength and athleticism wasn't needed.
