The "extraordinary" scale and duration of an alleged sex offender's crimes against teenagers he was supposed to be counselling has been revealed in court - including prior indecent dealing against a 15-year-old WA boy.
According to prosecutors, a sole complaint via Redress had eventually revealed that WA counsellor Allan Keith Huggins' alleged offending stretched back to the late 1970s, continued as late as 2010, and crossed State borders with allegations also being investigated in NSW.
Mr Huggins has not pleaded to more than 30 offences against seven men who had been teenagers when they were allegedly abused by the counsellor through his work.
Until recently he had been working as a counsellor in the Rockingham area and was described on websites as a leading academic in men's issues.
Police are now investigating the legitimacy of his credentials.
The charges allege that in 1990-1991 he abused boys who had seen him through services to help them.
Today, he appeared in prison greens on a videolink from Hakea Prison as his lawyer David McKenzie applied for bail.
But prosecutors opposed his release, citing a "strong case" and saying they had evidence that Mr Huggins had already been "convicted" in 1991 for indecent dealing against a 15-year-old boy that saw him handed a period of probation.
He also had complaints against him from when he had been a college master interstate.
The prosecutor said that by the time Mr Huggins came to WA he already had a "well-established propensity" to offend against people under his care.
The prosecutor said his offending started in the late 1970s and that one complaint was as recent as 2010.
"This is a man who has had an extraordinary long run of offending, mostly against people who were in some sort of vulnerability," the prosecutor said, describing the scale and duration of the alleged offending as "unusual".
A man in the back of the court, where some alleged victims had come to watch proceedings, shed tears as the court was told that a single Redress application had sparked a police search that uncovered Mr Huggins' diary from 1990-91.
Police had used the diary in their investigations and made contact with others who revealed similar allegations, the court was told.
The prosecution opposed bail, saying that aside from a strong case, they believed Mr Huggins could suffer vigilante attacks, was at risk of self-harm, and could interfere with witnesses or even commit further offences.
The prosecution also suggested Mr Huggins was a flight risk because of links to a foreign country.
But Mr McKenzie suggested there was no basis to the suggestions because while his client's boyfriend was from the Philippines, he was a permanent resident and that Mr Huggins' ex-wife, with whom he was still close, was also based here.
The court was told that Mr Huggins also had three adult daughters.The bail application was adjourned to next week after the magistrate wanted more material to support the opposition to bail.
