Nadal, Barty give Australian Open desperately needed happy ending

An Australian Open like no other began in controversy with the deportation of Novak Djokovic but culminated in one of the greatest comebacks in tennis history by Rafael Nadal on Sunday.

Throw in Ashleigh Barty becoming the first home winner for 44 years, and local heroes Nick Kyrgios and Thanasi Kokkinakis winning the men's doubles, this was a Grand Slam that will live long in the memory for myriad reasons.

After the chaos that preceded the tournament, Tennis Australia couldn't have dreamt of a happier ending -- and it was one they desperately needed, after a competition riddled with unforced errors on the organisers' parts.

It began with the spectacle of the nine-time Australian Open champion Djokovic being detained in a notorious immigration hotel, suffering multiple court cases and eventual deportation -- shocking no matter which side you sit in the Covid-19 vaccination debate.

When the first serve at Melbourne Park was struck on January 17, the world number one was in a Dubai airport transit lounge waiting for his connecting flight home to Belgrade.

It wasn't just the Djokovic saga that cast a shadow over the first Grand Slam tournament of 2022.

Tennis Australia had to make a hasty and embarrassing U-turn after instructing staff to prevent spectators wearing "Where is Peng Shuai?" T-shirts to highlight concern for the Chinese player.

They also had to justify a largely voluntary Covid-19 testing protocol that came in for criticism from some players, notably world number three Alexander Zverev.

They may count themselves extremely lucky that there were only a handful of virus cases.

Booing and screaming

Tennis Australia will no doubt bask in the glory of their two historic champions, Nadal and Barty.
