The Australian share market is home to a large number of shares, but not all make good investments. So, which ones could be?

Three top ASX 200 shares that analysts are recommending as buys are listed below. Here's why they could be among the best options for investors with $1,000 to invest in March:

CSL Ltd (ASX: CSL)

The team at Bell Potter thinks that CSL could be a top ASX 200 share to buy this month.

The broker feels that its shares are trading at an attractive level for investors. Especially given its belief that the biotech giant's earnings growth is about to accelerate after a sustained period of margin pressure.

It highlights that "CSL presents an attractive buying opportunity as we anticipate the start of a margin recovery phase for CSL, driving above-market earnings growth over the next few years. CSL trades at a 12-month forward PE of ~23x, representing a discount to its 10-year average of ~31x."

Bell Potter currently has a buy rating and $335.00 price target on its shares.

REA Group Limited (ASX: REA)

Another top ASX 200 share that has recently been recommended as a buy by analysts is REA Group.

It is the clear market leader in online real estate listings in Australia, operating the dominant realestate.com.au website.

Thanks to its domination, REA Group has been able to deliver consistently solid growth for over a decade and appears well-positioned to maintain this trajectory in the coming years.

The team at UBS believes this will be the case. As a result, the broker recently put a buy rating and $294.00 price target on the company's shares.

Treasury Wine Estates Ltd (ASX: TWE)

Lastly, Treasury Wine Estates could be a top ASX 200 share to buy according to analysts.

It is a leading wine company that owns a portfolio of iconic brands such as Penfolds, Wolf Blass, Lindeman's, and 19 Crimes.

Treasury Wine Estates has been going through a tough period but Goldman Sachs thinks investors should be patient and stick with the company. Especially given its relatively cheap valuation and positive earnings growth outlook.

Its analysts stated that "TWE is trading at FY26 P/E of ~15x, which is inexpensive relative to our Consumer coverage. If TWE is able to demonstrate added comfort to the market on its Penfolds channel sell-through and sustained US luxury portfolio growth, we expect the stock to re-rate positively."

Goldman has a buy rating and $12.90 price target on its shares.
