There are plenty of reasons to be an Optus customer at the moment. Not only has the telco introduced rollover data plans, it also enables you to pool your mobile data with your nearest and dearest.
The Optus handset range features all of the latest options, and as you'd expect, there are plenty of big hitters in there. Here are our picks of the bunch.
Sony Xperia Z5
Apparently James Bond uses one of these, and while it has plenty to offer, don't expect to operate your car via remote control or use it as a detonator or anything like that.
The Xperia Z5 is a welcome, but subtle overhaul to Sony's mobile offering. It's very recognisably in the same family as its Xperia Z3 predecessor, but its design manages to feel both thinner and lighter, without seeming slight. The addition of a stylish frosted glass back makes the Z5 the best looking phone Sony's ever produced.
One particularly noteworthy addition is the inclusion of a fingerprint sensor. Sony may be a little late to the game, but by positioning it one the side of the handset it's created a point of difference that's both practical and clever. Why hasn't anyone done that before?
Optus' plans for the Xperia Z5 start from $65 per month, for which you receive 500MB of data (let's not get carried away) and unlimited talk and text. At the other end of the scale, until January 4 Optus is offering 20GB of data and unlimited talk and text, along with 500 minutes of standard international calls.
Samsung Galaxy S6
There's was an enormous amount of hype leading up to the launch of the new Galaxy flagship, and rightly so. With bumped up specs and a stunning 5.1-inch Quad HD screen, the Samsung Galaxy S6 (and to a lesser extent the striking but gimmicky Samsung Galaxy S6 Edge) is by far the best handset Samsung has ever delivered.
Samsung's own octa-core Exynos CPU processor keeps things ticking along briskly inside the handset's beautifully elegant metal and glass chassis.
The hardware comes with a camera capable of some of the most gorgeous shots we've seen from a smartphone, a vastly improved fingerprint scanner (no more swiping), and a welcome simplification of Samsung's interface.
The S6 is a massive step up from the Galaxy S5, but if you're after something cheaper, you could always stick with last year's model.
Still, if you're happy in the Samsung family and the slightly-overbearing UI, the Samsung Galaxy S6 is the best Android handset around.
Samsung Galaxy Note 5
Samsung's latest S Pen-packing handset mimics the Galaxy S6's impressive build, but fans of previous Notes might take issue.
The Note 5 is by far the best-looking Note handset Samsung has ever produced. But the expandable memory and removable battery that fans have come to expect is conspicuously absent.
But there's no denying the Note 5's 5.7-inch screen is gorgeous, and its record-breaking processor and 4GB of RAM outpace Apple's current offering, as does its 16MP camera.
The leather back won't be everyone's idea of a premium material, but there's a lot to recommend the LG G4, not least of which is affordability. It's the most affordable phone here, with Optus offering it on plans starting from just $61 per month.
The G4's 5.5-inch Quantum IPS display vies with the Samsung Galaxy S6 for best screen on the market. And the camera offers a huge amount of control, delivering spectacular low-light results, while 'Auto' and 'Simple' modes remain for those that just want to point and shoot.
The battery life can have you reaching for your charger by the afternoon, but the G4's a very attractive smartphone for those looking for something a little different.
Apple iPhone 6S
As you would expect, the iPhone 6S is the most refined phone Apple has ever made.
While it first appears to be a more subtle upgrade than the iPhone 6 before it, there should be no mistaking that it's a significant step up.
The 6S takes everything that made the iPhone 6 such a great phone and runs with it. iOS 9 is as user friendly as on operating system gets, the camera consistently delivers impressive results, and this is a handset that packs some serious power.
The biggest improvement, however, is the introduction of 3D Touch. This enables users to interact with the phone in a variety of ways by applying different levels of pressure to the screen.
All of this adds up to quite a package, with quite a price to go along with it. While iPhones are always right up the premium end of the pricing scale, the 6S is a powerful, user-friendly phone that's worth the expense.
