Book series with teleporation tech, societal break down, and teenagers

Question

I listened to the audiobooks a few years ago, but cannot find a copy or history of checking it out from my library.

Things I remember about the book/series:

• Teenage, high school, female lead character
• Start of the book is at a jumper(?) party, where bored teens/twenty-somethings go to impromptu parties. These are sorta secret and can be an art. I think the character's first one is at an observatory
• Probably told in 1st person
• Released between 2008-2016, best guess
• House/apartments don't have stairs/elevators/doors, instead you can jump/teleport directly into your home
• Goods were either replicated or transported straight into the home
• Teleporting is actually cloning, but is controlled by a company/agency, who either goes rogue or gets hacked, starts wreaking havoc.
• Finds a boy who has never teleported, thus never having been cloned
• Teleporation can be done in large squares (unless I'm confusing stories...)
• Fights friends and/or a family member who died, but a clone was generated to deceive/kill the main character
• I believe the books were initially released in Australia and were given different names and covers in the USA
