A former university lecturer who used the internet to groom a child for sex will remain behind bars for Christmas.

Augusto Tamayo-Del-Solar on Wednesday had a bail hearing adjourned until January.

An ACT Supreme Court judge ordered he remain in custody until a judgement on a outstanding charge of committing an act of indecency was handed down.

The 61-year-old man last week sought bail to live at his brother’s Sydney home which is located across the road from a primary school.

Tamayo-Del-Solar’s legal team argued their client does not seek to be released until the Christmas holidays have begun.

But the prosecution argued it is unclear whether the Concord school runs after-school programs, and the location is "of great concern".

Tamayo-Del-Solar has been locked up on remand at the Alexander Maconochie Centre for almost three years.

The former Spanish lecturer was caught up in a police sting after allegedly grooming an 11-year-old for sex over the internet.

A federal agent, posing as the girl, took up the conversation and sent messages to the defendant about her end-of-year party.

In December 2009 they arranged to meet outside the Florey shops, where Tamayo-Del-Solar was arrested in possession of a pizza, Coke, a bottle of sparkling wine and condoms.

A search of his work later turned up explicit images of Tamayo-Del-Solar with an eight-year-old girl.

He pleaded guilty to procuring a child for sex, two counts of committing acts of indecency, using a child to produce pornography and possession child pornography.

But he denied committing an act of indecency on an 11-year-old in February 2009.

Tamayo-Del-Solar is accused of putting his hand down the girl's pants as they drove to an outing at a fast-food restaurant.

Justice Richard Refshauge heard the judge-alone trial in June last year and reserved his decision.

The judge adjourned the bail hearing until January when he intends to hand down judgement.

Justice Refshauge order Tamayo-Del-Solar remain in custody as the risk of bailing him to reside near a school “is unacceptably high”.
