Narrative:

My student took off on runway 18 at gtu airport and at 500 ft AGL started a turn to the southeast in order to fly to our flight school's practice area to the east of the airport. During our climb out; I heard a bonanza announce that he was 5 mi to the southeast; inbound on the 45 degree entry for the left downwind for runway 18 at georgetown. I mentally noted that this aircraft could pose a potential collision hazard. My student's heading was drifting left off course to 110-120 degrees instead of the 140 degrees I wanted for him to fly; I also mentioned that we had a bonanza inbound on the 45 degree. At this time we were at about 1200 ft AGL and departing the pattern. No sooner than I mentioned this than I observed the bonanza about 1 mi directly in front of us on a direct collision course. I pointed the traffic out to my student who hesitated; I immediately told him to turn to the right to avoid the traffic; which he then did. About 2 seconds later the bonanza must have also observed us and started a turn to his right. The bonanza passed off our left wing; at our altitude and about 300 ft away. We continued our climb to 1500 ft AGL before turning on course.

I POINTED THE TFC OUT TO MY STUDENT WHO HESITATED; I IMMEDIATELY TOLD HIM TO TURN TO THE R TO AVOID THE TFC; WHICH HE THEN DID. ABOUT 2 SECONDS LATER THE BONANZA MUST HAVE ALSO OBSERVED US AND STARTED A TURN TO HIS R. THE BONANZA PASSED OFF OUR L WING; AT OUR ALT AND ABOUT 300 FT AWAY.
