Jeffrey Scott Deacon, 28, is standing trial after pleading not guilty to one count of importing prohibited goods without approval.

The ACT Supreme Court on Monday heard that the Australian Border Force intercepted a parcel in September 2020 indicating the suspected prohibited goods from a sex doll-selling company in China.

The package was addressed to Mr Deacon at his house and it was intercepted in Sydney.

During the second day of trial on Tuesday, the jury was shown the $430 silicone doll.

A senior ABF investigator involved in the case stood the doll on the bar table and manipulated its body.

The digital forensic investigator also gave evidence about the data extracted from Mr Deacon's phone and his online search history, which included the phrases "small teen sex dolls" and "teen sex dolls".

Audio and video files of the investigation and an interview with Mr Deacon about why he ordered the doll were also played to the jury.

Mr Deacon said he was lonely and that he intended to order a "normal adult one" to "just have fun with it".

In his closing statement, prosecutor Ken Archer said the evidence, particularly the phone data and online search history, suggested Mr Deacon intended to buy a childlike sex doll.

He said the doll depicted someone younger than 18 years "because of the lack of obvious physical features that would suggest a more mature human being".

He said Mr Deacon was reckless about ordering a doll that had childlike features and that being ignorant that it was an offence to import such a product without approval was not relevant to the jury's deliberations.

"A reasonable adult would consider that the depiction of a child in that way ... would likely at the very least cause offence," Mr Archer said.

He said this recklessness was based on Mr Deacon's "preoccupation with young dolls" based on his online searches that included "teen dolls".

"They all centered around those sorts of concepts. They all have that sexual theme," Mr Archer said.

Defence lawyer Sam McLaughlin said his client was not reckless as he was not aware of the substantial risks associated with importing prohibited goods.

The defence lawyer said that what his client saw online when ordering may not be the product that arrived.

"He did not walk into a brick and mortar store and pull this item off the shelf," Mr McLaughlin said.

"There's no information as to what Mr Deacon saw, read, view prior to placing his order."

He also cited his client's evidence during a police interview about seeking an adult doll was consistent with his online search terms.

Mr McLaughlin said "teen" was as close as it got to his client searching for "child", although it was possible he came across childlike dolls.

"Mr Deacon told investigators he's dyslexic and doesn't read things," he said.

"He had no idea how big 100cm was even if he had read it. Just because someone's 106cm tall, it doesn't make them a child."

Mr McLaughlin said a Barbie doll, for example, may stand only 20-25cm tall but its small stature did not represent a child.

During the ABF investigation, they also found other items inside the package, including wigs, underwear and a device to heat up the doll.

Justice David Mossop will sum up the case on Wednesday before the jury deliberates.
