Correspondence associated with the dispute about Seven and the Australian Communications and Media Authority that Monis sent to other authorities, contain numerous references to "Martin Place" and "acts of terrorism", confirming his six-year obsession with the location.

Monis died along with two of the 17 hostages he took in the Lindt Cafe in Martin Place just metres from Seven's Sunrise studio last week.

The attack so near Seven has prompted speculation the Sunrise program or the channel itself was his initial target.

Monis' dispute, dating back to mid 2007, with ACMA and Seven also suggests his hatred for the channel was not triggered by Seven's current affairs expose of his anti-Afghan soldier letter-writing campaign and online videos in 2008.

Fairfax has learned the 50-year-old first complained in 2007 to ACMA about a Sunrise program broadcast on July 4 of that year.

He alleged that a guest on the program had commented about the Glasgow terror attacks and had indirectly provided instructions for terrorism and had therefore breached terrorism laws. He posted a quote supposedly taken from the program saying: "If you want to kill people, why not use the tools of your own trade like a plague or a disease or something? Why go into an area which you're clearly unqualified in."

In later ranting letters to other authorities about the Seven program he bemoaned their "failure" to investigate "terrorist acts at Martin Place, Sydney, Australia".

Monis also posted a comment on one of his websites saying he had asked authorities to condemn the Sunrise commentary as giving instructions to terrorism.

But he noted: "The attorney-generals of both governments and Mr John Howard and Mr Kevin Rudd has said to Sheikh Haron [him] that it was fine."

ACMA took Monis' complaints seriously enough to launch an investigation into whether the program had involved discrimination against Muslims and sought a copy of the program from Seven.

The complaint was later dismissed, infuriating Monis. ACMA has so far declined to provide a copy of the investigation report.

After learning the complaint was not upheld Monis wrote to ACMA expressing his disagreement with the findings but bizarrely congratulating the authority on its professionalism.

But for years afterwards Monis made reference to the Sunrise program.

Throughout 2012, he maintained a website on which he posted just one statement which said: "That from 2001 I was silent, I was dead.

"Until 4th July 2007 I was in a deep sleep. Sunrise woke me up! God can awaken a person by many different means even by a terrorist broadcast from the program Sunrise on Channel Seven from the Australian TV!

"I thank God and I won't give up until the Australian government condemns that broadcast which was instructing terrorism".

On Friday, a spokesman for Channel Seven said the station was making no comment on Monis while the siege investigation was ongoing.
