There are plenty of reasons to be an Optus customer at the moment. Not only has the telco introduced new rollover data plans, it also enables you to pool your mobile data with your nearest and dearest.
The Optus handset range is a curious mixture of old and new, and naturally it includes all of the best and brightest from the big names.
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.
Apple iPhone 6
Is it fair to describe the iPhone as an "oldie but a goodie"? After talking about the iPhone for as many years as we have, it is the first thing to pop into our heads.
Of course, the iPhone 6 (or the iPhone 6 Plus if you're into scale) is the latest and greatest in Apple's arsenal, and is among the best phones in the Optus catalogue.
It sports a far more powerful processor than the iPhone 5S, excellent camera, and the battery life has improved dramatically.
Keep in mind though that the iPhone 6S or 7 is likely to be coming out in a few months time. If you want an iPhone, we recommend you holding off till then, because even if the next iPhone ends up being out of your wallet's range, the 6 will see a significant price drop.
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.
HTC One M9
Following up the HTC One M8 can't have been an easy task, but the HTC One M9 keeps all the best bits and adds an extra layer of polish, refreshing things just enough to make it one of our most recommended smartphones on the market right now.
The design is still spectacular – even if the two tone variations aren't for everyone – and it should keep the competition on their toes in terms of styling.
For the camera, HTC's ditched its Ultrapixels approach, adopting a 20.7MP sensor instead. The results are impressive, increasing sharpness and losing the One M8's tendency towards over-colouration.
The battery life hasn't improved since the last generation, and the handset can get a little warm, but this is nitpicking.
More of a refinement than a complete overhaul, don't be surprised if you want this phone once you've held it for yourself, even if HTC is no longer the clear leader in the Android market.
