Teen breaks leg killing spider

A 19-year-old youth-camp leader has broken his leg in two places after kicking ''one of the largest'' huntsman spiders he had ever seen.

The teen saw the spider on a wall this morning while at the Attunga Country Campsite in the NSW Southern Highlands and attacked it with a deadly kick that ended the spider's life - and badly affected his own.

He was airlifted to Liverpool hospital by an NRMA CareFlight helicopter from the camp, which is 25 kilometres west of Mittagong.
