Frank,
Data can be transmitted from Smart Meters at either 15min or 30min intervals (possibly at other rates).
The Standard appears to be 30mins (the NEM standard allows for the 15 or 30 min rate) for most users.

Basically from what I can gather, data is transmitted from your smart meter to YOUR ELECTRICITY SUPPLIER, who in turn send the data to your retailer (AGL in this case).
The data from your supplier is sent on-wards to your retailer who then supply the data to you on a daily basis. Not every 30 mins.
This would require quite a bit of computing power as the meter reads would need to be examined, tested for accuracy, then the retailer determined and the data sent to them.
Firstly you can get the data directly from your supplier in most cases.
I am in SA, I have signed up with my supplier (SA Power Networks - SAPN) and I can download the data from them most days after about 9:00 am (09:00) for midnight, yesterday, whilst to get the same INFORMATION from AGL takes ANOTHER 24 or 48 hours.
The data from SAPN is supplied in NEM format (basically a row of 48 meter readings for each half hour of the day) in Meter order
Data Date 00:30 01:00 /////// 23:30 24:00
| 300 | 20190428 | 0.217 | 0.228 | ~~ | 0.191 | 0.191 |
While the data from AGL is presented in the format you are used to if you download from your My Usage page.

As you can see the NEM format data is easily read (specially in a S/Sheet).
You may also notice that they data supplied by AGL is incorrect because they are trying to fudge the information due to the fact that I am in SA and THEY DO NOT KNOW HOW TO HANDLE IT.
Which is in my favour, as my bill is always less than what it should be.
Now in answer to your question, will you able to see the data in near time in this decade.
Probably, it may appear, but there are technical details that you have to think about.
1. What do expect to see. The last 5, 10, 15, 24 hours or all of the data at the time you request it.
2. Is their any advantage in doing so.
3. There is technology now that allows you to see individual power usage in your home and AGL are trialing this I believe.
If you look up the manual for your smart meter you will find you can do a few things.
I can see my current consumption in AMPs and Watts or I can see my output to the Grid in AMPS and Watts, the frequency of my ac, the voltage of my ac, my current meter readings for all of my supplies etc etc.
Having current data (ie now) does not have any real benefit for me as I am interested in the trends I can obtain from analysing the data over a period of time.
For instance consumption at 12:00 on a week day will consist of whatever fridge is running at the time. While on a weekend 12:00 consumption will be completely different, the washing machine going, I am welding up a project in the shed or machining a part, Mary is cooking a a cake etc.
For instance here are the last three days for my usage up to Midnight 18 April.
Well would you believe I cannot do this right now because of Technical Difficulties with SAPN web site.
NMI: 20XXXXX: A technical issue has occurred which prevents the retrieval of NMI details. We apologize for this inconvenience. Web service callout failed: Failed to get next element.
Oh well not that important, I can do it later or maybe even tomorrow.
Cheers
Neil
