Drew Scott was spending a lazy Sunday afternoon on his back patio with a beer and tending the barbeque when the unthinkable happened – a venomous brown snake slithered directly beneath his chair.The 34-year-old Gold Coast resident, whose alarming encounter with the dangerous reptile yesterday afternoon was captured by his home CCTV camera, said he would have been none the wiser had his dog not alerted to him to the snake’s presence.“I saw the dog come around and she growled and [when] I looked down I saw the snake,” he told 9news.com.au.“The first thing [I did] was to jump away and make sure I got the dog inside straight away ‘cause I was concerned she might get bitten.”aHis three and five-year-old children were playing just metres away inside his home and Mr Scott said the snake then slithered under the fence and into an adjacent park reserve.
