That comes despite the government launching a working group in 2017 aimed at increasing their availability.
Senator Fifield says there is no legislative impediment to TV broadcasters rolling out audio descriptions, but it hasn't happened.
"It is clear that that has not been taken up," he told a Senate estimates hearing on Tuesday.
The minister said he would ask broadcasters how they could offer audio descriptions and what level of coverage they believe they could achieve.
He stressed public broadcasters should be ahead of the pack.
"The ABC and SBS should be leading by example in this area," he said.
The Australian government funded the ABC to run a 13-week trial on ABC1 in 2012 and the second on ABC's online catch-up service iView in 2015-16.
Both were well-received by those with vision-impairment, according to the audio description working group's 2018 report.
"The feedback received by the blindness sector consumer groups indicated that the first AD trial on ABC1 in 2012 was the first independent experience of television for some consumers who have been blind from birth," the report states.
"For others who experienced a loss of vision later in life, access to AD allowed them to rediscover the medium of television."
Labor says Australia is the only major English-speaking country yet to have audio description on TV.
"This isn't good enough," opposition communications spokeswoman Michelle Rowland said.
"The Abbott-Turnbull-Morrison Government has been dragging its feet."
