Although the caretakers had complete faith the baby turtle would recover well and grow to become healthy and robust, they were worried that it spent six whole days "defecating plastic," given its size.
"So, for a little turtle this size, every single day, no faeces came out, just pure plastic," said Taronga veterinary nurse Sarah Male in a video uploaded by the zoo.
"We do have all of the plastic... we've collected it and counted how many days, and we came up with six tiny vials full of all different sizes of plastics," she said.

Male said plastic is pretty much all the turtles eat because "there's so much" around.
She further noted that the turtle was "lucky" because some of the plastic it ate and passed out "was really hard," so it could've caused a blockage.
"This guy... just say luck was on his side!" Male said.
Although the turtle has had tremendous progress since the plastic exited his system, it may take an entire year before it's released back into nature.
Unfortunately, the incident with the baby turtle isn't uncommon for Taronga's Wildlife Hospital, which cares for up to 80 marine turtles annually.
Many of those turtles are admitted into the hospital with significant injuries as a result of plastic and hook ingestion as well as getting caught in fishing lines and crab pots.
"If everybody just takes a little bit of their time to pick up a bit of rubbish – it doesn't have to be on the beach – then hopefully we can make a difference," Male said.
Plastic pollution in oceans continues to be an extensive problem, but small steps towards change are being made.
