Consumer journalist Sinead Ryan says anyone with tickets for events that have been postponed should check with their ticket seller.
The presenter of The Home Show on Newstalk told The Hard Shoulder concert tickets are a grey area, as opposed to airline tickets.
"Wasn't it with a charming naivety this time last year that we thought 'Sure everything will be up and running, back by summer'... and here we are now, looking even as uncertain this year.
"People have confusion over tickets, some of the companies selling tickets aren't clear on their own policies and what's going to happen.
"The problem, really, is that ticket sales come in under general contract law - in that there's not a specific, universal law say that pertains to flights which is covered in its own legislation.
"And as such, with contract law, you are subject to the terms and conditions that the company itself sets down".
She said this means people could be subject to different terms depending on the ticket seller, the venue or the event itself.
"Unfortunately, there isn't a universal set of rules that says 'You're entitled to refund in Case A or in Case B'.
"The only time you would be entitled to a refund is if they breach the contract - so for instance, you're due to attend a concert... [and] the concert gets cancelled, never to be held again and therefore you're entitled to your money back.
"Now that doesn't apply where you've taken out what's called a person to person transaction.
"For instance, if you bought your ticket off your mate in work, or off a second seller website, that's not neccessarily going to be the case".
And she said some events could still be in the process of being rescheduled.
"In some cases they're saying 'We haven't got around to rescheduling a date because we haven't got a licence, we've to check with the promoters, or the band is touring elsewhere'.
"Where that's the case, they're saying 'Hang on, we'll let you know' - that might sound unfair, but it's not an outright cancellation and therein lies the problem".
"You're not entitled to refund just because you don't think it'll go ahead - you'll be entitled to refund if they don't let it go ahead".
In terms of holiday bookings, Sinead explained that most companies - such as hotels or accommodation providers - offered people their money back.
However she said people who made individual bookings ran into trouble.
"So it's where you're doing a person to person contract: that has no rights in consumer law at all - whether the accommodation is in Ireland or abroad.
"But once done through a travel agency or through a hotel chain, where they physically can't open the doors, that's an absolute no problem there - you will get your money back".
