When my Children were born ~8yrs ago, my parents opened up a saving account for them through CBA (Dollarmite ac - I am the guarantor on the account))and have been regular making monthly payments , so one day they will have a reasonable saving account established. My parents recently mentioned that they will be contributing a further lump sum for each of their grandkids of 10K in each of their accounts. My mother said that noone is to touch the money, and hopefully in the longterm (ie until they are in mid 20'swith interest there would be growth with the money that they will be able to enjoy in the future. I mentioned to my parents that we should look at setting up a sharing trading account for each child, liked to their account and look at buying some blue chip share and let them take their cours over the next ~12-15yrs. Dad was all for it, mum being a bit more old school didn't didn't feel that comfortable with the idea, but after explaining the potential difference in growth in shares vs saving, she could unerstand what I was talking about. With the above mentioned in mind, what do you guys recommend would be the best way to invest this money for reasonable to high growth over the period involved? Ideally, the investment vehicle should somehow be linked with their savings account, as my parents will still contribute on a monthly basis. Also, is there anything we need to be aware of in relation to tax etc as I'm listed as guarantor on the accounts and also that the kids are under 18. Thanks in advance.
