Ricciardo finished the race in second place but was disqualified five hours later after his car was found to have exceeded the 100kg/h fuel flow limit.
Red Bull strenuously denied breaching the regulations, but the Milton Keynes-based outfit ultimately lost its appeal after a hearing in Paris on Monday.
In a statement, the team said: “Infiniti Red Bull Racing accepts the ruling of the International Court of Appeal today. We are of course disappointed by the outcome and would not have appealed if we didn’t think we had a very strong case.
“We always believed we adhered to the technical regulations throughout the 2014 Australian Grand Prix. We are sorry for Daniel (Ricciardo) that he will not be awarded the 18 points from the event, which we think he deserved.
“We will continue to work very hard to amass as many points as possible for the team, Daniel and Sebastian (Vettel) throughout the season. We will now move on from this and concentrate on this weekend’s Chinese Grand Prix.”
Riccardo also commented on the news, saying: “It’s disappointing not to get the 18 points from Australia, but if anything it gives me more motivation to get back on the podium as soon as possible.
“I’m still really happy with my performance in Australia and for having had the experience of being on the podium in front of the home crowd. I said that week, I’d rather have a great race, finish on the podium and then be excluded than to have had a rubbish race and then retire with a car problem half way through.”
