geoffGeoff Topham - Founder of GnorTop

Geoff has had many a varied experience in the electrical field, most of which was some 30 years at Port Hedland working for BHP (now BHP Billiton Iron Ore). Before moving to Darwin in 2001, he began apprentice training in 1996 with BHP, and became the department's training co-coordinator. ​

He continued with training apprentices when he came to Darwin - firstly for NTU, then for Training Solutions, and then onto CDU. In 2004, he started GnorTop, conducting and writing training courses as a sub-contractor to another RTO. In 2007, he opened the Winnellie Office and applied for RTO status, in order to offer high quality training and assessing to the NT in some of the National Training Packages. He's since obtained & continues to maintain RTO status, which allows GnorTop to office Nationally accredited training packages.

In July 2010, he decided to move GnorTop to their new office in Parap, which offered bigger office space in a prime location. Whilst the new office allowed further expansion of the opportunities & courses GnorTop offered, after almost 5 years, it was decided it still wasn't quite the right fit.

So, in May 2015, he decided to move GnorTop back to Winnellie, close to where he started GnorTop in the first place. Within the new single level office, GnorTop has one large training room available, where all the magic happens. And with GnorTop now settled into their new location, this allows for further courses to be run & further opportunities to see why people in the NT are talking about GnorTop.
