Mate, if there's anything I've learnt it's that lagers are HARD. Anyone can make beer, but it's not easy to make good beer.
If you think the recipe is the answer then it's time to step back and look at brewing - hops, rests, fermentation temps, time, water, sanitisation, yeast, yeast management, patience etc. etc.
It's complex and requires skill to make beer. It requires more technique to make a good lager than an ale even though at the end of the day, you will make beer.
Not trying to shoot you down but get onto making beer and making lots of it. If you think 'lager' is the stuff on the tap at most Aussie pubs then you might be in trouble. Many brewers have tried to make VB, New and the like and can't (even though some/many will argue it's not worth it). There are so many nuances to it that - especially considering you don't have the grain specs and yeast - ultimately replicating megaswill can't be done on the home brew level. You'll get close, but not there. If you're good enough you'll get better, and THAT'S when the real satisfaction sets in.
When you say you can't get them right, what are you expecting? Do as Stu say, skip a secondary (in my opinion) and just give it more time. Make sure your yeast is rehydrated and ensure you can get your FG down to around 1.008. What have you been achieving?
